Super Spin Wheel...
Give it a spin in battle, and you’ll crush everyone.
Use it while learning combat techniques, and you’ll master them in no time.
But for a few days every now and then, it goes haywire... Like a woman on her period, one moment it won’t eat anything cold, the next it won’t eat anything hot, then it wants to go shopping, then it wants to smash things... In short, it does all sorts of unpredictable things, completely at random...
