Hildie and Beatie return from the Ol' Time Goblin Fair with kettle corn, a giant stuffed warlock, and a piranha they won in the ball toss. Despite their warning not to touch the fish, Tom can't pass up a chance to eat the catch of the day! But first he has to get past Jerry who is determined to protect his new friend. When a failed attempt by Tom ends up with the fish bowl being shattered, Jerry quickly casts a spell with the wand that allows the fish to breathe on dry land! The liberated fish is excited to explore his newfound freedom (walking on his tail fin) and ends up making life a lot more complicated for Jerry who's trying to protect him!
