All Grown Up!

When a comic book starring Chuckie's favorite superhero Armadillo Dave gets cancelled, he becomes too depressed to help Tommy with his science fair project. Tommy has to buy a rat for his project, but the last rat available is a mean one. It scares everybody. Kimi made Tommy a simple one lane track for his rat, much to his disappointment as he feels he would get a failing grade for it, but needs Chuckie so he can get a good grade on it since Chuckie has done it before. The gang tries to find Chuckie a new hero to worship.
