When humans build a housing development in their forest, a group of animals work together with a scheming raccoon to steal food. The animals clashing with humans they've never seen before allowed a lot of room for comedy. This is a good movie, but I'm not sure the story completely worked. It felt a bit disjointed and focused more on setting up gags than actually building the plot.
I also don't think it's held up well over the years. The animation is unique and has a sharp visual style, but looks a bit stiff compared to current animation. Of course, this is a problem with all early computer animation, but Pixar wisely avoided animating certain objects like people and fur until they had the technical skill to render it realistically. This one didn't. Everything looks stiff and a bit plastic. But the family enjoyed it, and we had a few good laughs.
