Orchestral Maneuvers in the Park

There's going to be a jazz concert at the Youth Center! Curtis wants to play his & Zack's uncle's famous trumpet. It ends up getting stolen and turned into the Trumpet Top monster. His musical blasts cause the Power Rangers to hallucinate, making them think they're fighting monsters they've already defeated (including Stag Beetle, Grumble Bee, Praying Mantis, Lizzinator, Slippery Shark, Fighting Flea, and more).
