"A Sticky Situation" contains the following tropes:
- Alliterative Name: The owner of the hardware store, Stan Sandpaper.
- Argument of Contradictions: TJ and Becky arguing over whether to watch the Pretty Princess and Magic Pony Power Hour or Real-Life Shark Wrestlers is eventually reduced to them just yelling "Princess" and "Shark Wrestlers" at each other.
- Astonishingly Appropriate Appearance: Stan Sandpaper the hardware store owner has hair shaped like a hammerhead while his fiancée, the woman who owns the radio shop, has hair shaped like a radio.
- Big "NO!": Granny May gives one right before she's captured at the end of the episode.
- Bread, Eggs, Breaded Eggs: Becky thinks Mrs. Botsford's figurine looks like a penguin while TJ thinks it looks like a snowman. Turns out it's a penguin snowman.
- …But He Sounds Handsome: When Becky accidentally comes home still dressed as WordGirl, she tells TJ that his "amazing sister Becky" asked her to give him the glue she bought.
- Chained Heat: WordGirl accidentally gets her back glued to TJ's while trying to fix their mother's figurine, forcing her to stop Granny May's crime spree while stuck to him.
- Coincidental Broadcast: Just after Becky and TJ break their mother's figurine, there's a news broadcast revealing that the hardware store is closing early, so anyone who needs some glue for, say, putting together something valuable they broke had better hurry. Lampshaded when the anchorwoman signs off calling it "the oddly specific news".
- Ignoring by Singing: When WordGirl asks TJ to close his ears for a second so she can have a private conversation with Captain HuggyFace, he obliges by covering his ears and humming.
- Instantly Proven Wrong: As the episode begins, the narrator claims that Becky and TJ "always play nice". Cut to them fighting over the remote control to the TV.
- Oh, Crap!: After Granny May gets away from the radio store, WordGirl bemoans that she's probably halfway home by now. Then it sinks in for her what she just said and she realises that Mrs. Botsford will be home soon to see her broken figurine.
- Paper-Thin Disguise: As port of a scam, Granny May buys a drill from the hardware store disguised only with a hat, pair of sunglasses, and fake mustache. She doesn't even bother to change out of her dress.
- Punctuated! For! Emphasis!: TJ does this when he goes on about how he and WordGirl are on a mission against time to fix Mrs. Botsford's broken figurine.TJ: But together, they might... just... do it!
- Squee: This is TJ's immediate reaction when he realises that he's stuck to WordGirl.
- Steven Ulysses Perhero: The hardware store owner is named Stan Sandpaper.
"Eight Legs vs. Two-Brains" contains the following tropes:
- Ahem: WordGirl does this to get the attention of Dr. Two-Brains and his henchmen when she flies in on them turning milk into nacho cheese. She does it again later at the farmers' market when Dr. Two-Brains gets distracted by his henchmen driving away in the truck he just found out they had.
- Class Pet: Shaggy the tarantula is a temporary version. As part of a class assignment, every student has to take a turn to bring him home and observe him.
- Comically Cross-Eyed: Downplayed. The old woman who owns Shaggy has either this or Fish Eyes in a few shots to emphasise her being slightly harmlessly off.
- Continuity Cavalcade: When Becky remarks on how messy TJ's room is, various outfits of his from previous episodes can be seen scattered on the floor, such as his minigolf outfit from "Putt With Honor" and his elf costume from "Castle! Dungeon! Fortress! So?".
- Cut Lex Luthor a Check: Dr. Two-Brains' plan du jour is simply to turn milk into nacho cheese and sell it so he can use the money to pay for his ray guns. The only really illegal part of the plan is that he stole the cow he uses to get the milk.
- Giant Spider: Subverted. The episode opens on what seems like a giant spider climbing the school, but it turns out to just be the Class Pet, Shaggy the normal-sized spider, climbing a miniature replica of the school.
- Here We Go Again!: After Becky has dealt with her arachnophobia and Shaggy has said his goodbye to the class, a man comes in with the next class pet: a huge snake.
- Hope Spot: Downplayed. When Becky doesn't want to take Shaggy home with her because of her arachnophobia, Violet offers to do so instead. Unfortunately, taking him home is a class assignment and Becky is the only one who hasn't had a turn, so she has to take him.
- I Can't Believe I'm Saying This: After conquering her arachnophobia and growing to like Shaggy, Becky has this to say:Becky: Well, I never thought I'd say this, but I love that tarantula. Well, maybe not love, but I can touch him!
- Screams Like a Little Girl: This is the narrator's rather understandable reaction when he sees what he thinks is a giant spider climbing Woodview Elementary.
- Security Cling: WordGirl clings to Captain HuggyFace when Shaggy starts to escape his terrarium.
- Spider People: The woman who owns Shaggy the tarantula inexplicably has four legs, though unlike most examples of the trope she's benign besides a slight case of Creepy Monotone.
- Sudden Soundtrack Stop: The suspenseful music that plays as Dr. Two-Brains is cowering from Shaggy stops when WordGirl points out that Shaggy isn't even doing anything.
- Tempting Fate: Subverted. The narrator declaring it "another safe and pleasant day" is interrupted by a giant spider climbing on the school building, but then it turns out it's just a regular-sized spider on a scale model.
- Troubled Fetal Position: Dr. Two-Brains goes into one when scared into submission by Shaggy at the end of the episode.
- Versus Title: "Eight Legs vs. Two Brains".
- Your Other Left: A rare instance of "your other right" is used when Dr. Two-Brains is trying to direct his henchmen on where to move the suspended cow whose milk they're making nacho cheese from.
