* ''WesternAnimation/TheSecretOfNIMH2TimmyToTheRescue'':
** Timmy, whose constant arrogance and tendency to act before he thinks often puts himself and worse yet his friends in danger all throughout the movie.
** Martin, for having run away from home out of jealousy of Timmy even when NIMH was still about searching for the rats.
** Everybody in Thorn Valley, for having been so eager to fashion Timmy into a hero because of Nicodemus' warning of worse things yet to come from NIMH; ironically, their actions in reverence to this prophecy may have inadvertently put their home at even greater risk than it otherwise would've been; see SelfFulfillingProphecy on the film's page.
* ''WesternAnimation/{{Thumbelina|1994}}''. Every time she gets kidnapped, she keeps letting the kidnappers take advantage of her. She could be excused since she's lived a sheltered life, but common sense should have stepped in at some point and while she does eventually stand up for herself, it's not until the last ten minutes of the movie. Yeah...
** Let's not even get in to her not asking that goddamn bird to fly her home but instead trying to ''walk it.''
* ''WesternAnimation/MickeyDonaldGoofyTheThreeMusketeers'' has Mickey getting this temporarily when confronting Pete about his wrongdoing. He stands tall and alone against someone much bigger and stronger than he is instead of making a strategic retreat to get Goofy (who he doesn't know has been captured) or some other reinforcements.
* In ''WesternAnimation/RugratsGoWild'', Spike seems to be pretty clever for a dog. He spends a musical number dodging and humiliating a huge leopard... but then he stupidly mentions that there's a group of lost, helpless infants somewhere on the island, and the leopard immediately goes looking for them to eat them.
* In ''WesternAnimation/RiseOfTheGuardians,'' Jack falls for Pitch's BatmanGambit, and searches through Pitch's lair, [[ItMakesSenseInContext looking for his teeth.]] When he finds the teeth, and returns to the other Guardians, the others immediately come to the (admittedly reasonable) conclusion that Jack is in league with Pitch. Clearly, Jack found the teeth ''and'' the idiot ball in the lair, because at no point does Jack attempt to explain, and the whole thing could have been avoided with one sentence. "I found where Pitch is keeping [[spoiler: the tooth fairies.]]"
* In ''Film/RaceForYourLifeCharlieBrown'', it's Peppermint Patty's diplomatic voting. For one thing, it's massively one-sided: it only deals with the girls and their decisions end up screwing over the boys (including ''kicking out the boys out of the house that '''they found''' and leaving them in the snow''). Second of all, the things they vote for is things that would require ''simple common sense''. Of course, it's Peppermint Patty -- common sense and that girl never got along.
* In ''The Incredibles 2'',
** The kids repeatedly ignore the fact that removing the incredibly fragile mindcontrol goggles that are controling the other supers are all they need to do to win. This can be excused early on as they may have been caught off guard by the situation. As the movie progresses though it becomes more ridiculous. The kids have powers nearly designed to snatch goggles. (Super speed and invisibility) and make no attempts to do so. Worse at certain points the mind controled supers are rendered unconcious at their feet and they still don't take the goggles off. Instead they just leave them in that state for some reason.
** Villain captures elastigirl and rather than killing her or forcing her to go kill innocents in public rampage. Villain lets her regain her senses in order to monologue about villain plan.
** Makes villainous plan to discredit supers overly complex. It is literally foiled by a baby. All plan needs is public acts of terrorism by supers. Instead of sending supers to do this villain has them guard a boat!?
** Villain reveals their identity to elastigirl for no reason. Was given multiple opportunities to brainwash elastigirl without disclosing identity. After capturing hero instead of erasing memory of their identity which they would seem likely to have or killing her. Incriminates themselves capturing mr incredible.
** Villain falling to death kicks hero in face making it harder to save their life.
