Core-uption Catscratch : Season 1 Episode 30

Kimberly’s teacher fails her on her project: a model of the earth’s core, made of glitter, cotton candy, rainbows, and other pretty stuff. Seeing Kimberly upset, Gordon travels to the center of the earth, and tosses her project into the core! And the earth transforms! Clouds turn into cotton candy, unicorns roam freely, and it rains glitter! But as the cats soon learn, too much of a good thing can be really, really awful.
