Squiggz, Cosmo and Flutter are having a great day on the boardwalk, that is, until the arcade is invaded by the biggest, meanest exterminator the kids have ever seen. So the kids race to find Grandpa, who's fishing in a restaurant lobster tank, and he tells the wonderful story of David and Goliath. This inspires Squiggz to face down his own "giant" in a hilarious battle, and the young roach realizes that it doesn't matter how big you are. What matters is the size of your heart.
