Super Hero Worship (S05E04)

After Chuckie's beloved comic featuring his favorite superhero, Armadillo Dave, is abruptly canceled, he spirals into a deep funk, leaving him unable to assist Tommy with his science fair project. Tommy desperately needs to buy a rat for his presentation, but the only one left is a nasty creature that frightens everyone. Though Kimi creates a straightforward one-lane track for the rat, Tommy is disheartened, fearing he'll receive a poor grade without Chuckie's help, as Chuckie has experience with this type of project. Meanwhile, the group sets out to find a new hero for Chuckie to admire.
