On Fins and Needles

Jason & Tommy teach free karate classes at the Youth Center. Rita's annoyed by their friendship, and sends down the Slippery Shark monster. His boomerang-fin weapon casts a spell on the two, causing them to hate each other intensely. This nearly leads to an all out brawl in the Youth Center, organized by Bulk & Skull. Luckily, their teammates intervene, and by forcing teammwork, Tommy & Jason break free from the spell and sink the shark.
