* AntiClimaxBoss: Subverted. [[spoiler:Dennis is built up as a major threat but crushed by the Cyclops moments after he finally catches up with the heroes before he can do much to them... Then he comes back and the ''actual'' fight with him takes place.]]
%% No Complete Monsters in SpongebobSquarepants. Comedic Sociopathy played for laughs =/= CM
* EnsembleDarkhorse: Dennis.
* GoodBadBugs: In the final boss of the Video Game, a broken plank on the floor behind Krabs leaves you safe from [[spoiler: Neptune's]] attacks.
* SugarWiki/HeReallyCanAct: [=SpongeBob=] is known for being goofy and immature, but in this movie, Creator/TomKenny does an ''outstanding'' job at [[TearJerker making the audience cry]]. Especially during the gift shop scene.
--> ''[[DarkReprise I'mmm]]'' [[DarkReprise a Goofy Goober, yeahhhh...]]
** Not to mention that brief HeroicBSOD at the edge of the trench, where [=SpongeBob=] realizes how immature he is for his age. Hearing the guy sound so panicked and frustrated with himself is quite a shock.
* HoYay: Spongebob and Patrick, of course. One notable example would be when Spongebob imagines Patrick having [[ShesGotLegs long, woman legs with fishnets]] during his singing of "Goofy Goober Rock." Spongebob even [[DistractedByTheSexy gets all wide eyed and excited when Patrick does the splits with said legs.]]
* MagnificentBastard: Plankton finally becomes this, as he succeeds in an EvilPlan for perhaps the first time ever.
** Possibly the best example would be Plankton ''successfully'' framing Mr. Krabs for stealing the crown, with a simple phone call. But what really makes it it Plankton smirking, listening to Neptune scream.
--> '''Plankton:''' "Plan Z. I ''love'' Plan Z!"
* MemeticMutation: [[http://i1.ytimg.com/vi/g33PYjkPy0s/maxresdefault.jpg Surprised Patrick]], from his reaction following AlwaysABiggerFish. Pretty odd, considering the fact that the movie came out nearly ten years ago and has only recently become a meme - and the fact that [=SpongeBob=] was there pulling the exact same expression, yet he does NOT have the same Memetic status as Patrick (a fact that is lampshaded in [[http://i1.kym-cdn.com/photos/images/original/000/529/102/1a3.jpg this image]]).
* MoralEventHorizon: Plankton definitely crosses this when he steals Neptune's crown, frames Mr. Krabs for it (knowing very well that he'll be executed), brainwashing and enslaving Bikini Bottom and hiring Dennis to kill SpongeBob and Patrick. He takes it even further at the climax when he [[spoiler:brainwashes King Neptune to not only kill SpongeBob and Patrick, but also kill Mindy, ''his own daughter''.]]
* PuritySue: Princess Mindy, arguably due to her FlatCharacter status mentioned above.
* ShockingSwerve: [[spoiler:Spongebob suddenly having the ability to turn into a rock warrior/wizard at the climax of the film.]] Nonetheless, it's still awesome to watch.
* VisualEffectsOfAwesome: Between the beautifully deranged animation, great use of the RogerRabbitEffect, and other special effects, this is one great looking movie.
* WhatDoYouMeanItsForKids: SpongeBob and Patrick get drunk off of ice cream, and wake up with hangovers.
** Mind-controlled slaves, a few deaths, and a violent hitman.
