McGee
Voiced by: Scott McCord
The protagonist. A reckless and enthusiastic 12-year-old thrill-seeker who views Camp Lakebottom as a place of fun and adventure.
- Anime Hair: His hair seems naturally spiky.
- Annoying Younger Sibling: McGee's prankster traits probably made him an example to Suzi, but he's otherwise always ready to stick up for, and help his older sister. She rarely reciprocates.
- Berserk Button: Don't call Camp Lakebottom lame and don't mess with his friends or the counselors.
- Butt-Monkey: Things tend to not go his way quite often, although he usually manages to come out in once piece by the end.
- Determinator: He doesn't give up easily.
- Didn't Think This Through: A Running Gag on the show (and practically his Catchphrase) is the fact that he tends to not think things entirely through with his plans.
- Freaky Is Cool: Once the initial confusion is cleared up, McGee quickly takes to Camp Lakebottom.
- Guile Hero: In general, he's usually the one who comes up with the plan, even if they don't always work out the way he intends.
- Hot-Blooded: His eager but somewhat impulsive attitude makes him fun-loving and adventurous.
- Jerkass Ball: His mischief and disobedience can make him fall into this.
- Keet: He's an incredibly energetic and excitable young lad with a love for fun and adventure.
- The Leader: Between him, Gretchen, and Squirt, he is the one who drags them onto whatever adventure they're up to and comes up with the plans that get them out of sticky situations (or get them into said situations).
- Like Brother and Sister: He gets along much better with Gretchen than he does with his actual sister Suzi.
- Nice Guy: He's a very kind, laid-back, helpful, friendly (and if not a bit insensitive, mischievous, disobedient and selfish) bottom-dweller to have around.
- The Prankster: He loves making mischief, especially when the targets of his practical jokes are Camp Sunnysmiles.
- Vomit Discretion Shot: He vomits after the spider was sucking up a fly
- Why Did It Have to Be Snakes?: He really hates spiders.
Gretchen
Voiced by: Melissa Altro
One of McGee's two best friends. A sardonic girl who is more than capable on taking the various horrors Camp Lakebottom has to offer.
- Action Girl: She's trained in martial arts and often puts her skills to use fighting monsters and other freaky things.
- Affectionate Nickname: McGee and Squirt sometimes call her "Gretch".
- Alliterative Name: In "Meet the Gretch's Parents", her surname is revealed to be Grietchelson.
- Aloof Dark-Haired Girl: She has black hair and is noted for her snarky, aloof personality.
- Can't Catch Up: Ever since Gretchen lost to Suzi in the Miss Sunnysmile paegent, she has dedicated her whole life in order to prove that she can match up Suzi. However many of her attempts to compete with Suzi only further prove her inferiority. Suzi is prettier, smarter, and more popular than Gretchen,and thus she hardly acknowledges Gretchen's existence and only sees her as an utter annoyance. To add insult to injury, Suzi takes any opportunity to ridicule and humiliate Gretchen and lets her know who is better.
- Catchphrase: "Ya think?"
- Cute Bruiser: A 12-year-old Perky Goth with martial arts training that allows her to kick monster butt.
- Deadpan Snarker: She has a sharp tongue, especially when it comes to McGee's dafter plans
- Expressive Hair: Her pigtails sometimes stick up straight when she's scared.
- Girlish Pigtails: She wears her hair as two large pigtails.
- I Know Kung Fu: Her martial arts training gets brought up quite often and frequently helps her contribute to the plot of an episode.
- The Lancer: As the more grounded and sensible of McGee's two friends, she often plays the role as his Number Two.
- Like Brother and Sister: She has a sisterly sort of relationship with McGee.
- Masculine Girl, Feminine Boy: Her sardonic personality makes her the Masculine Girl to the soft-hearted Squirt's Feminine Boy.
- Only Sane Man: Is generally more level-headed than the other campers.
- Perky Goth: While she's snarky, she generally has an upbeat attitude.
- Tall, Dark, and Snarky: She's the tallest of the three main kids, with black hair and a snarky attitude.
- Tomboy with a Girly Streak: She's the Tomboy to Suzi's Girly Girl, but she's also competed in the Miss Sunnysmile pageant (though she apparently will deny being upset about coming in second place to Suzi if asked).
- Unknown Rival: This one's been a bit exaggerated. She has a one-sided rivalry with Suzi and always tries to match up to her. Suzi, one the other hand, only sees Gretchen as every other girl who's ever tried to compete with Suzi.
- Why Did It Have to Be Snakes?: She's terrified of chipmunks and thinks they're evil. Turns out she's entirely justified.
Squirt
Voiced by: Darren Frost
The other best friend of McGee. A chubby and naive but cheerful boy who can't help but show kindness to all living things.
- Acrofatic: Despite his rotund appearance, he can be quite nimble when the situation calls for it.
- The Beastmaster: He's very good with animals, being able to befriend and communicate with nearly every wild animal the kids encounter.
- Big Fun: He isn't slim, but he is a cheerful and kindhearted boy.
- Catchphrase: "Stop that! You're scaring it," usually when someone is threatening an animal.
- Cloud Cuckoolander: He can be rather... unusual sometimes.
- Companion Cube: His underpants, who he calls "Gitchie." (Gitch is a Canadian euphemism for underwear.)
- Fat Best Friend: He's McGee's plump but good-natured buddy.
- Friend to All Living Things: At one point, he stopped McGee from using worms as bait, calling them his friends.
- Friend to Bugs: He even makes friends with flies and spiders.
- Gasshole: Prone to pulling off some very massive and powerful farts.
- Genius Ditz: Although naive, he's very knowledgeable about animals, correcting identifying Armand as a Sasquatch and knowing the difference between a rooster and a chicken.
- Gentle Giant: The largest of the trio as well as the nicest.
- Masculine Girl, Feminine Boy: His gentle but naive personality makes him the Feminine Boy to the aloof and sardonic Gretchen's Masculine Girl.
- Nightmare Fetishist: His Friend to All Living Things status extends even to monstrous creatures like giant spiders and the tentacled monster living in the lake.
- The Pollyanna: He always looks on the bright side of life.
Sawyer
Voiced by: Cliff Saunders
One of the counsellors at Camp Lakebottom. A zombie with a multipurpose tool on his left hand and actually quite a friendly guy - even if his body keeps falling apart.
- Friendly Zombie: Sawyer is an all round Nice Guy who plays with the kids. While he does snack on brains, which he keeps refrigerated in a fridge, he makes it a strict rule to never harm the campers. His mother on the other hand is a stereotypical brain eating zombie who wants to make her son follow in her path.
- Handy Man: He serves this role around Camp Lakebottom. His Swiss-Army Appendage proves useful in that regard.
- Intergenerational Friendship: With the campers, whom he serves as a sort of father figure to.
- Meaningful Name: Sawyer is frequently equipped with a saw on his left hand.
- Nice Guy: He's about the furthest you can get from your stereotypical mindless, ravenous, zombie in terms of personality.
- Our Zombies Are Different: A Friendly Zombie who eats refrigerated brains and acts as the Handy Man.
- Papa Wolf: Don't mess with his campers.
- Swiss-Army Appendage: His left arm is usually substituted with a chainsaw, but it can be swapped out for things like fishing rods, toilet plungers, and nets.
- Tagalong Kid: Adult version. Sawyer is usually the one who accompanies the campers on their escapades.
Rosebud
Voiced by: Jonathan Wilson
Another of Camp Lakebottom's counsellors. A short, stout, and surly old woman with a German accent who cooks up Camp Lakebottom's disgusting meals.
- Action Girl: She's quite capable in a fight.
- Ambiguously Human: She certainly looks human, but with the other counselors being a zombie and a Sasquatch, some people wonder...
- Apron Matron: She's tough-as-nails and looks after the campers like they were her own children.
- Brawn Hilda: Especially in flashbacks to when she was young. She even sported pigtails and a horned helmet.
- Camp Cook: She makes the revolting meals that the kids and counsellors eat.
-
Cross-Dressing Voices: She's voiced by a guy. - Funny Foreigner: We only know that she's from a town called Freizuncoold in the old country.
- Lethal Chef: The theme song of the show even lampshades it! The fact that she uses some nasty ingredients doesn't really help. Sawyer and Squirt seem to like her subatomic chilli poppers though.
- Masculine Girl, Feminine Boy: Her tough and surly attitude makes her the Masculine Girl to the sensitive and sophisticated Armand's Feminine Boy.
- The Napoleon: Don't let her diminutive size fool you, Rosebud is not to be messed with.
- Pintsized Powerhouse: She's able to carry Armand with ease, even though he's easily three times as big as her.
- Retired Badass: She used to be the deadliest monster hunter alive, but after she captured a young Armand and Sawyer and prepared to send them to a Prison Dimension, Sawyer's stomach started growling, so she offered to make the two of them a snack before chucking them through the portal. She enjoyed cooking for them so much that she spared them and became their full-time chef.
Armand
Voiced by: Adrian Truss
The last of Camp Lakebottom's counsellors. A sensitive and sophisticated sasquatch with a passion for the performing arts and fashion.
- Bigfoot, Sasquatch, and Yeti: He's a large brown-furred Bigfoot.
- Camp Straight: His interests include typically feminine fare like art and fashion, but he has shown interest in women sometimes.
- Cute Little Fangs: Has tiny fangs visible from his jaw even when his mouth is closed that surprisingly add to his soft personality.
- Gentle Giant: He's rather Camp Straight, for a sasquatch.
- Half-Dressed Cartoon Animal: He's only shown wearing shorts and a scarf.
- Large Ham: Being an enthusiast for the fine arts, especially theater and cinema, he's very dramatic.
- Living a Double Life: He's also a secret agent of the Tuxedo and Martini variety.
- Masculine Girl, Feminine Boy: His campy interests and sensitive personality make him the Feminine Boy to the surly Rosebud's Masculine Girl.
- Real Men Wear Pink: He wears purple shorts and a pink scarf.
Suzi
Voiced by: Bryn McAuley
McGee's older sister and a former pageant queen. She is a vain and spoiled girl who attends Camp Lakebottom's rival, Camp Sunnysmiles.
- All Girls Want Bad Boys: She has a crush on the obnoxious and arrogant Buttsquat.
- Aloof Big Sister: To McGee, whom she generally showed very little compassion or sympathy towards.
- Alpha Bitch: A summer camp version. She's vain, spoiled, bossy, always wants to be the center of attention, and hangs out with all the rich, popular kids at Camp Sunnysmiles.
- Always Someone Better: To Gretchen since she won the Miss Sunnysmile pageant while Gretchen was runner up.
- Arch-Enemy: To Gretchen. Suzi beat her at the Miss Sunnysmile pageant and will never let her live it down.
- Attention Whore: Suzi must always be the best most prolific person in the area, even if it means letting her little brother get hurt to stay at the top. Or say cursing an entire play and calling upon dark curses that leave her a lightning shooting, wild-haired monster.
- Beauty Contest: Competed in a few of these prior to the series.
- Beauty Is Bad: When it comes to high school beauties, Suzi is unparalleled, and does a lot more than simply set the standard for what it means to be pretty. However, she doesn't have the personality to back it up. Suzi knows she's beautiful, and she's going to make that fact darn well clear to everyone else.
- Berserk Button: Suzi is perpetually annoyed at just about everything she comes across and has little to no tolerance for anything. Any unfortunate soul that manages to annoy her just enough is going to have to deal with an entire gallon of whoopass, courtesy of the terrifying Suzi. After all,in "Stage Fright", she's given more than enough reason why messing with her is a bad idea. In short... NEVER. EVER. CROSS. SUZI.
- Big Sister Bully: She's a bit mean-spirited to her brother.
- Dreadful Musician: She's a horrible singer, although completely unaware of this.
- Humiliation Conga: Inverted. Even though Suzi only sees Gretchen as an utter annoyance, rather than an actual rival, she finds it rather arrogant whenever Gretchen has the nerve to try and compete with her. So in order to teach Gretchen a lesson (as well as for her own amusement), Suzi often humiliates and ridicules her in some of the most extreme ways possible.
- Insufferable Genius: Suzi has, an always will be, a constant source of jealousy for many girls, especially Gretchen. Suzi knows this and takes every opportunity possible in letting everyone see just how much better she is. With unrivaled intelligence, beauty, popularity, talent, etc., it's no wonder why people want to be her. She enjoys seeing the hopeless reactions of those wish they could be like her but can't, especially Gretchen.
- Jerkass: She's an all-around mean and selfish Alpha Bitch type, although she does have more sympathetic moments compared to Buttsquat.
- Lovable Alpha Bitch: Despite her cynical and sadistic personality, Suzi is surprisingly popular among her peers. Although, considering that everyone else in Camp Sunny Smiles is almost as cynical as her, it probably isn't all that surprising. Aside from that, Suzi is still incredibly likable, even to her little brother, who she constantly abuses on a regular basis.
- Moral Myopia: In "Head Two Head," she claimed that she's "always nice," ignoring her antagonistic personality.
- Never My Fault: In one episode, Suzi and Buttsquat have jet skis. Suzi invites her brother to join her only to close a glass door on him every time he tries to accept her invitation. She blames him when the mechanism that opens and closes the door breaks.
- Pink Means Feminine: She's a classic rich and popular Alpha Bitch who wears a lot of pink in most of her outfits.
- Pride: Considering Suzi's position, she is naturally confident in her abilities and pretty much sees herself as royalty.
- Tomboy and Girly Girl: Her Alpha Bitch personality makes her the Girly Girl to the Perky Goth Gretchen's Tomboy.
- Ungrateful Bitch: No matter how many times McGee saves or helps her, she shows him zero gratitude.
- Valley Girl: Frequently speaks like one.
Jordan Buttsquat
Voiced by: Carter Hayden
The archrival of McGee and his friends, as well as Suzi's crush. He is the smug and spoiled son of the owner of Camp Sunnysmiles.
- Alpha Bitch: Male version. The most popular guy in Sunny Smiles and definitely not nice.
- Arch-Enemy: To McGee. Their rivalry is the driving force of many episodes' conflicts.
- Attention Whore: He's always seeking to be the center of attention in some way.
- The Caligula: Being the son of the owner of Camp Sunnysmiles means that he pretty much runs the show and there's no stopping his tyranny. He even went as far as to ban gum from the camp.
- Catchphrase: "I will have revenge!"
- Cycle of Revenge: He seeks revenge on McGee and the others for past defeats. This just leads to him being defeated again, and swearing more revenge.
- Dirty Coward: Prone to fleeing and abandoning anyone else he's with at the first sign of a monster.
- Evil Redhead: Has red hair and is not a nice guy.
- Fiery Redhead: He can be loud when he needs to, and again, is red-haired.
- The Gadfly: He takes great pleasure in tormenting McGee and his friends.
- Jerk with a Heart of Jerk: He is a very unpleasant child and he very few times he does seem to show some degree of sympathy or redemption is usually quickly subverted afterwards.
- Karmic Butt-Monkey: No pun intended. He often gets roughed up as much as McGee due to karma.
- Last-Name Basis: Rarely is he referred to as Jordan. Might be justified with the fact that his enemies would prefer calling him by his questionable surname. Plus, for whatever reason, he seems to prefer calling himself by his surname as well.
- Miles Gloriosus: He regularly acts like he's braver and more capable than he really is.
- Rich Bitch: His parents own Camp Sunnysides, and their money enables him to afford all kinds of expensive things.
- The Rich Want to Be Richer: His parents are rich enough to give him yachts (out of packs of ten), yet Buttsquat often tries to butt in on the Bottomdwellers' treasure hunts, and take the treasure for himself.
- Sitcom Archnemesis: To McGee. He's not so much evil as he is mean and annoying.
- Spoiled Brat: He's the phenomenally wealthy son of the owner of Camp Sunnysmiles, as well as a smug and whiny little jerk.
- Unfortunate Names: Yes, Buttsquat actually is his surname. And yes, he's been ridiculed for it by the others.
- Ungrateful Bastard: Has antagonized McGee right after McGee saved his life.
