Fashion Mystery

The Fashion Mystery is a treasure that is unlocked when the player scans the Rosalina amiibo from the Super Mario Bros. series in. It looks just like the amiibo, and is worth.

Collecting the treasure
After scanning the amiibo on the area selection screen (in any sector), the treasure will appear in one of the Secret Spots of the area. Then, the player has to retrieve the Fashion Mystery in that spot.
