The Giant Gyroscope

Professor Mushroom scrunched up his mushroom cap, wiggled his stump, and muttered some magical words. POOF! In a cloud of sparkling red and gold dust, the most enormous gyroscope ever appeared right in the middle of the room! It was magnificent - all shiny metal spinning rings, four times bigger than Nani himself, with a comfortable leather saddle perched at the very top. Nani's eyes grew as wide as saucers. It was perfect!
