History Film / ScoobyDooMonstersUnleashed

* CanonForeigner: The Cotton Candy Glob was created for the movie and never appeared in any of the Hanna-Barbera cartoons.

* BalloonBelly: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that causes him to transform into a monster with a big, protruding belly, which noticeably jiggles as he lets out a BurpOfFinality after drinking another potion that turns him into [[WesternAnimation/LooneyTunes the Tazmanian Devil]].

** While in Jonathan Jacobo's underground laboratory, Scooby attempts to create an antidote using two potions. Shaggy throws one of the potions across the room and Scooby shouts, "Nooo!"
** The Evil Masked Figure [[spoiler:after Scooby puts the control panel back in the machine and before the monsters start dying.]] They let out another as they are unmasked, that changes from the Evil Masked Figure's voice into [[spoiler:Heather Jasper-Howe]]'s voice once the mask comes off.
* BitByBitTransformation: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that makes him abnormally muscular, starting with each individual arm and working its way down his body.
* BizarreAlienLimbs: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that causes him to transform into a monster with stubby arms and six tentacles in place of his hind legs.
* BlindShoulderToss: While searching for an antidote in Jonathan Jacobo's underground laboratory, Shaggy looks at a potion and then, deciding it isn't the right one, tosses it over his shoulder. After drinking the following potion, he does the same thing with its container.

* BrainsAndBrawn: While in Jonathan Jacobo's underground laboratory, Scooby and Shaggy drink various chemicals/potions that cause them to transform in various ways. In their final forms, before taking the antidote, Scooby becomes ludicrously intelligent and Shaggy becomes abnormally muscular, making the duo fit this trope to a T.

* ChemistryCanDoAnything: While in Jonathan Jacobo's underground laboratory, Scooby and Shaggy drink various chemicals/potions that cause them to transform in various ways.

* DigitalHeadSwap: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that gives him a "Chick's body," but has no effect on his head. This was achieved by compositing Matthew Lillard's head onto Nazanin Afshin-Jam's body.

* FindTheCure: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that causes him to transform into a monster. While searching for an antidote, Shaggy accidentally transforms as well and must find a cure for both of them.

* ImminentDangerClue: Despite being in Jonathan Jacobo's underground laboratory, covered in warning stickers, and primarily full of liquids, Scooby mistakes the refrigerator full of potions for a regular refrigerator containing food, and consequently, mistakes a yellow potion/chemical for lemonade. He doesn't realize his mistake until after his ObliviousTransformation, when Shaggy points out that he's transformed.

* TookALevelInKindness: In response to criticism regarding [[AdaptationalJerkass their depictions]] in the previous film, the members of the Mystery Gang are noticeably less mean-spirited and self-centred in this instalment, bringing them closer in line with their original cartoon counterparts.

* BalloonBelly: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that causes him to transform into a monster with a big, protruding belly, which noticeably jiggles as he lets out a BurpOfFinality.

** The film pretty much ignores the events of the 2002 film.

->'''Shaggy''': This is tied for the most terrifying day of my life!\\
'''Velma''': Tied with what?\\
'''Shaggy''': Every other freaking day of my life!

* BaitAndSwitch: [[spoiler: When Daphne reveals Howe had an accomplice, Patrick looks scared out of his mind. Daphne then reveals the accomplice was Howe's cameraman, Ned.]]

** Velma considers [[WesternAnimation/APupNamedScoobyDoo Chickenstein]] one of most ridiculous foes they’ve faced, but Shaggy and Scooby recall that he tried to pluck them at one point.

--> '''Daphne''': Taste the pain, Mr. glow-y, ugly, thing!

--->'''Fred''': And the real identity of [[spoiler:Ned]]] is--\\

'''[[spoiler:Ned]]''': Ow!\\

'''Fred''': ...[[spoiler:Ned]]!

** [[spoiler: Though the movie tries to make it look like Howe is innocent by having the Evil Masked Figure appear seconds later, he reveals his motive is to take over Coolsville. This is not the motive that was mentioned earlier or later, where it was strictly revenge. This implies that this Evil Masked Figure is not the real one.]]

'''Fred''': [[LampshadeHanging He stole]] [[BuffySpeak my thing]] [[CatchPhrase that I say]]!

--> '''Freddie:''' Hey! You're doing that thing again where you take everything I say out of context! ''You're'' trying make it look like ''I'' think Coolsville sucks! [''realizes he's being filmed''] No! Don't record that!

'''Scooby''': ''[completely nonplussed]'' Hello.

** [[spoiler:Velma's LoveInterest, Patrick, who has a StalkerShrine to [[BigBad Jonathan Jacobo]] located not far from the Evil Masked Figure's lair, and even admits to having admired the latter's work]].

** Shaggy and Scooby angst that they are always TheLoad who never contribute anything in solving the case. This ignore several times in the original series that they managed to either find a clue or even catch the ghost such in ''"A Clue for Scooby Doo"'' where Shaggy (in one of his defining moment at the time) is the one who discovers the identity of the Ghost of Captain Cutler, something even Velma couldn't solve. Also, when lamenting their failures, Shaggy claims that they plowed into the Snow Ghost because they accidentally glued their feet to rocket powered roller skates. In "That's Snow Ghost!", Shaggy threw a snowball at the Snow Ghost which turned into a giant snowball which grabbed the Snow Ghost and the gang.

'''Fred:''' ...Nick!

* MotorcycleJousting: Fred rides a motorcycle to duel a knight ghost.

'''Fred:''' ...Ned!

-->'''Shaggy:''' Alright, gang! Let's, like, split up, and search for clues.\\
''[the gang split up]''\\

The film is noticeably more kid-friendly than the first film, and was an even worse failure critically (winning a Razzie for "Worst Remake or Sequel"), and grossed around $180 million, making a profit, but not as much as Warner Bros. had expected. While this did signal the end of the full feature films, Warner would go on to make two live action made-for-TV prequels five years later: ''Film/ScoobyDooTheMysteryBegins'' and ''Film/ScoobyDooCurseOfTheLakeMonster''.

* BladeOnAStick: Daphne uses a halberd when dueling the Black Knight.

%% * GettingCrapPastThe Radar: Due to overwhelming and persistent misuse, GCPTR is on-page examples only until 01 June 2021. If you are reading this in the future, please check the trope page to make sure your example fits the current definition.

* BroadStrokes: The film pretty much ignores the events of the 2002 film.

* CanonCharacterAllAlong: The "Evil Masked Figure" is a new identity for [[spoiler: Jonathan Jacobo, as is "Heather Jasper-Howe."]]

* PteroSoarer: Double subverted; the Pterodactyl Ghost is obviously not supposed to look like a real pterodactyl. However, Velma analyzes one of its scales to find that it's "a ''real'' pterodactyl scale". Real pterosaurs didn't have scales (they had hairlike fibers on their bodies).

* IgnoreTheFanservice: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that gives him a "Chick's body," but rather than pulling a ManIFeelLikeAWoman and exploring his anatomy- like Fred does while in Daphne's body in the first movie- Shaggy verbally acknowledges his new form while pointing to his GagBoobs and then just continues searching for an antidote.

* GagBoobs: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that gives him a "Chick's body," featuring considerable breasts that are near the center of the frame for every shot of him in this form. During his transformation, two popping noises and an EyeTake imply that these breasts are springing out from his chest. Shortly after his transformation, he points toward them with both hands. While in this form, he often stands with his shoulders back, making them even more prominent. When he checks the fridge in this form, he leans farther down than he did in his original form, giving the camera a direct shot down his shirt that reveals his jostling cleavage.

* ButterFace: When Shaggy drinks a potion that gives him a "chick's body", it's a [[ImpossibleHourglassFigure shapely]] female body in a revealing GenderedOutfit... that still has Shaggy's unchanged head. Matthew Lillard is by no means an ugly man, but his head still looks wrong on that body.
