* That confrontation just before the scene with the bear. And of course, [[BearsAreBadNews the bear itself]].
** In particular, right after Amos wounds the bear's shoulder. It roars in pain, then looks down at Amos with a SlasherSmile that the ''Joker'' would be proud of.
** It gets even scarier on Amos' part: that was a protected forest, he was never supposed to be there in the first place. There wouldn't be any other people for miles around. He is essentially AloneWithThePsycho in the middle of the wilderness, and this bear could snap his bones like they're toothpicks. Thank goodness Copper was there to come to the rescue!
* The confrontation between Tod and Copper at the den. You want to see what a '''real''' DeathGlare looks like? [[NightmareFace That kind of snarl]] is what an animal does when it intends to defend something to the death - and no less.
** The look on Copper's face is no better. Let's put it in perspective--he spent the better part of the movie looking like a happy, lovable non-anthropomorphic [[{{Expy}} Goofy]]. Then shit happens, he blames Todd for it, and now he's looking like a straight-up HellHound as he tries to drag his former friend out of his own home and kill him.

* The effects of rabies and strychnine on their victims. And the way strychnine just ''keeps'' passing up the food chain. Both are made all the more awful by being chilling TruthInTelevision.
