Barrel of Laughs

The Barrel of Laughs is a treasure that is unlocked when the player scans the Diddy Kong amiibo from the Super Mario Bros. series. 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 Barrel of Laughs in that spot.
