History Film / ScoobyDoo

* Fainting: Scooby, after being told that if he and Shaggy ccept the offer to go to Spooky Island, they will be given an all-you-can-eat deal.

** [[spoiler:The fact that Scooby is particularly important (his soul is the purest one to be absorbed through the Daemon Ritus) are hinted at first of all with the whole thing with the hamburgers in the woods before the castle scene and again when Shaggy and Scooby run into the possessed rock band and possessed-Fred says, "Get the dog."]]

* FreakyFridayFlip: Mystery Inc. minus Scooby after [[spoiler:their souls were transferred to different bodies. After a few switches, they end up back in the correct bodies.]]

* TheFriendsWhoNeverHang: As the film is set-up with an acknowledgement to the animated series, Velma is annoyed at being the odd man out yet again during the obligatory LetsSplitUpGang (Shaggy & Scooby, Fred & Daphne). Fred volunteers to partner up with her, but as they don't hang, Fred struggles to carry a conversation with her, but she appreciates the effort.
* GameFace: The possessed students eyes glow green. [[spoiler:When Mary Jane is hit in the face by a branch, it's literally bent out of shape, revealing her as a monster in disguise, though only Scooby notices.]]

* NiceJobFixingItVillain: [[spoiler:Despite only needing Scooby for the ritual, Emile Mondavarious/Scrappy-Doo invited the ''entire'' gang of Mystery Inc. to the island when the members had already broken up and went their separate ways two years ago, just so that they can witness his moment of triumph. This subsequently results in the previously-hostile Scooby Gang rekindling its relationship and coming together to defeat Scrappy's plan.]]

** It's pretty much guaranteed that, in addition to having stunted growth, dogs will also be mentally disabled. [[spoiler: Scrappy can perfectly impersonate a polite, successful businessman and keep up that masquerade and everything it required for over two years m,..]]

* ArtisticLicenseBiology: Velma mentions that this continuity's Scrappy-Doo was not a puppy,
but an adult with a glandular disorder. Hormonal balance disorders causing dwarfism in canines do exist, but there are several more symptoms then just being smaller then average-lethargy and sickliness in general comes to mind, while Scrappy seems to be in perfect health (in particular, very lively) other then allegedly stunted growth. Dogs with such disorders also don't live very long without regular treatment, so Scrappy would have died shortly after being ditched in the middle of nowhere with no medical support.

but an adult with a glandular disorder. Such disorders do exist, but a prominent symptom of them is lethargy and in general sickliness, while Scrappy seems to be in perfect health other then allegedly stunted growth. They also don't live very long without treatment, so Scrappy would have died shortly after being ditched in the middle of nowhere with no medical support.

* GettingCrapPastTheRadar:
** An oral sex joke didn't get past the radar and was removed to lower from an R rating to a [=PG=].
** Shaggy mentions that "But you don't need to know what 'Voulez-vous coucher avec moi' means to love that song!" Kinda justified in that it ''is'' in a song, but it still means 'Do you want to sleep with me?'. If Shaggy really ''doesn't'' know what it means, [[FridgeBrilliance then it's even more justified, since]] ''he really doesn't know what he's saying''. However, it was removed in the book.
** Velma says "crap" once she saw Daphne at the airport.
** Daphne tells the crew she plans to open a can of "Chinese whoopass".
** Daphne heavily implies that the Luna Ghost kept trying to grope her. It was altered to bad breath in the book.
** Also the scene right after the gang has broken up with Scooby and Shaggy hanging out at a beach, in their van, laughing, whilst smoke comes out of the van's roof. It turns out they're really just making eggplant burgers. The burgers in question feature some [[BizarreTasteInFood rather unusual condiments including chocolate and hot sauce]]. Also, "Pass the Dutchie" is blaring in the background.
** Related to that smoke, when Mary Jane first introduces herself, Shaggy enthusiastically notes that she has his favorite name. ([[DontExplainTheJoke Mary Jane is a nickname for marijuana]])
** Shaggy and Scooby also won't go anywhere with "Hydrocolonic" in the name, but that's like, for a totally different reason, man.
** When Shaggy finds Fred [[spoiler:after the monsters attack]], Fred drops the word "biatch". Subtitles render that as "bitch".
** Right before the gang kicks Scrappy out of the group, he outright tells Fred, "You dont have the Scrote for this job, Pally!".
** And finally, ''this'' awkward line, spoken by Fred [[ItMakesSenseInContext while in Daphne's body]]: "Hey... I can look at myself ''naked''!" Immediately afterwards he [[ManIFeelLikeAWoman looks down the front of her shirt]] and grins. Later, Fred-in-Daphne's-body can be seen in the [[FunnyBackgroundEvent background]], groping her own breasts. Also Shaggy-in-Velma's body can be seen trying to look up her own skirt.

* EvilUncle: [[spoiler: Inverted. It's actuall ''Scrappy'', Scooby's nephew, who's the villain.]]

** In the cartoons, Shaggy's first instinct when facing anything spooky would be to run. However, whenever his friends were in danger he would almost always come through and try his best to rescue them. After Fred and Velma are capture by monsters, he's initially more than willing to abandon them.

** Velma in one of her outfits, [[spoiler:plus in a deleted scene, a bikini]].

* HeterosexualLifePartners: A rare man and man's best friend case -- Shaggy and Scooby-Doo. They're best friends and always look out for each other, and as such are nearly always seen together. For example, when Scooby falls down the hole during his argument with Shaggy, Shaggy dives down after him to try and find him. He's the first to actively decide to rescue Scooby after it's discovered [[spoiler:Scooby's soul is the pure one needed for the demons' ritual.]] He also tries to [[spoiler:attack Mondavarious to stop the actual absorption from happening.]]

* NiceJobFixingItVillain: [[spoiler:Despite only needing Scooby for the ritual, Emile Mondavarious/Scrappy-Doo invited the ''entire'' gang of Mystery Inc. to the island when the members had already broken up and went their separate ways two years ago, just so that they can witness his moment of triumph. This subsequently results in the previously-hostile Scooby Gang rekindling its relationship, coming together to defeat Scrappy's plan.]]

* OneWingedAngel: [[spoiler:Scrappy after absorbing the souls.]]

** Daphne for a brief moment, [[spoiler:when she's first captured by Zarkos]]. Plus Velma in one of her outfits, [[spoiler:plus in a deleted scene, a bikini]].

** Yet ''another'' bit of drug humor: Scooby and Shaggy mention that they won't go anywhere with "hydrochronic" in the name. Hydrochronic is the name of a very potent form of marijuana, grown hydroponically.

* TookALevelInBadass: Daphne had a radical change from her classic DamselInDistress characterization. Elements of this change stuck around in future ''ScoobyDoo'' media, notably in ''WesternAnimation/WhatsNewScoobyDoo''.

** Also played straight with Emile Mondavarious's initial introductory scene when he was revealed as a hidden person operating a large greeting robot from the inside. Later, [[spoiler:it was revealed that Emile Mondavarious is actually a robot being operated from the inside by a hidden Scrappy Doo all this while because the real, human Emile Mondavarious have been put aside and imprisoned by Scrappy two years earlier.]]
* ChekhovsHobby: Daphne mentions after the gang meet up at the airport that she undertook becoming a blackbelt. [[spoiler:This comes in handy during her fight with Zarkos at the end.]]

** In the Latin American Spanish dub and also overlapping with RoleReprisal of sorts, Arturo Mercado Sr., who regurlarly voiced Shaggy in the animated adaptations until the 2010s, voiced [[spoiler:Scrappy]], a role he voiced as well, while his son, Arturo Mercado Jr., voiced Shaggy instead.

** Played straight with Shaggy showcasing his skill at manipulating the claw machine game to win a plush shrunken head toy for Mary Jane. During the climax, [[spoiler:this skill came in handy when he needed to manipulate the pincher machine to rip the Daemon Ritus from Scrappy's chest.]]
** Also played straight with Emile Mondavarious's introduction scene when he was shown to be a hidden person operating a giant greeting robot from the inside. Later
[[spoiler:it was revealed that Emile Mondavarious is a robot being operated from the inside by a hidden Scrappy Doo all the while. The real, human Emile Mondavarious having been locked up two years earlier by Scrappy.]]

** Played straight with Shaggy's skill at manipulating the claw machine game to win a toy for Mary Jane. In the climax, [[spoiler:this skill came in handy when he needed to manipulate the pincher machine to rip the Daemon Ritus from Scrappy's chest.]]

* OhCrap: A LOT of them.
** The Luna Ghost seems to have one at the start before Shaggy and Scooby slam into him while hanging off the hook.
** Scooby in the woods when he sees the monster that sneaked up on him.
** Said monster has one just before being subjected to a TreeBuchet.
** Daphne in the castle just before a ride wagon slams into her soon after the power is turned on. Fred and Velma get one too at the same time when the suits of armor either side of them swing pikes at them and another wagon comes up from behind. Also at the same time, Shaggy and Scooby when they get tied up and held against the wall.
** All of Mystery Inc. get one in the castle when the small henchman sets off the security alarm. Then again moments later when they see the shadows of Zarkos and several others coming towards them.
** Scooby after [[VillainsOutShopping N'Goo Tuana's piano performance]] [[DoubleTake after seeing a monster's face in the window next to him]].
** This line from Fred:
-->'''Fred:''' There's absolutely, absolutely, no such thing as..." ''(one of the creatures bursts in)'' "...[[OhCrap MONSTER!]]"
** Shaggy, Daphne and Mary Jane get one when they see Scooby is about to accidentally push them out of a window. Scooby as well when they're about to go through the window.
** Shaggy and Scooby when [[spoiler:possessed-Fred and several others breathe green gas at them]], as they just realized they are possessed by the creatures.
** Daphne when [[spoiler:Zarkos captures her.]]
** [[spoiler:Possessed-Fred]] just before Shaggy and Scooby smash out of the garage they are trapped in on two quad bikes.
** [[spoiler:Any monster that gets exposed to sunlight has one, seconds before exploding.]]
** Shaggy after Velma's WhamLine. [[spoiler:He's just realized the pure soul needed for the ritual is Scooby's.]] Accentuated by a zoom into his face as he makes the realization.
** Two more in quick succession at the start of the climax. Fred has one when he realises the ritual is beginning earlier than expected. Then Shaggy has one when he realises the cable he attached to the protoplasm vat (that Fred and Velma are about to rappel down on) is clipped through his own karabiner.
** Shortly after that, a henchman gets one just before Shaggy slams into him and knocks him out.
** Scooby after hearing from [[spoiler:Scrappy that his soul would be needed for Scrappy to transform into Scrappy-Rex.]]
** Zarkos at the end [[spoiler:after Daphne overpowers him and he realizes she's about to get her own back on him.]]
** [[spoiler:Scrappy, coupled with a BigNo, when Shaggy uses the pincer to remove the Daemon Ritus from his chest.]]

** Also the scene right after the gang has broken up with Scooby and Shaggy hanging out at a beach, in their van, laughing, whilst smoke comes out of the van's roof. It turns out they're really just making eggplant burgers. The burgers in question feature some [[BizarreTasteInFood rather unusual condiments]]. Also, "Pass the Dutchie" is blaring in the background.

* AdaptationalVillainy: [[spoiler:Scrappy-Doo]] of all people is the BigBad.
