Shadow and Sassy (Chance was busy elsewhere at the time) entering a burning building to save a boy and his kitten that they met earlier who were trapped inside. All four make it out alive, and the boy overcomes his fear of dogs as a bonus.
Chance turns the tables on Ashcan and Pete when they attack Shadow and Sassy. He convinces them to follow him and tricks them into a tube, which he rolls downhill - just like he did to Sassy earlier in the film.
Chance: Hey, what's got eight legs, no brains, spins around and screams like a baby? Pete: I dunno, what? Chance: You guys! (shoves the tube with Ashcan and Pete inside down the ramp, screaming all the way down)
