Mini Diddy Kong
From the Super Mario Wiki
Mini Diddy Kong is a wind-up toy in Mini Mario & Friends: amiibo Challenge who is based on Diddy Kong. He is unlocked when the player scans a Diddy Kong amiibo onto the Wii U GamePad. His unique ability, called the Ledge Grab, enables him to grab any platform's ledge that can be located below the cliff or platform he has fallen from. Once he climbs it up, he moves on from the ledge.
