These purple 4-point-star-shaped things you'll find in levels are the main in-game currency in Inanimate Insanity Miracles.

During the Miracle Effect, you'll see smaller versions of them, worth a tenth of it's normal counterpart! Just like Super Mario Bros. Wonder's flower coins, obviously.

Twinkles can be spent on the shop to buy profile backgrounds, profile foregrounds, profile frames, and costumes for playable characters!
