Billy encounters the undertoad and barely manages to return to the beach. With the dangers of the sea avoided, the kids head home, but the undertoad is determined to take down Billy, so it follows him home. The next day, the undertoad becomes a constant nuisance for Billy, even at school. Grim and Mandy capture the undertoad and take it out on a boat to release it into the sea, where they encounter the giant Mama undertoad.
