Mini Diddy Kong
From the Super Mario Wiki
Mini Diddy Kong is a new wind-up toy making his first (and so far only) appearance in Mini Mario & Friends: amiibo Challenge. Mini Diddy Kong is only unlocked when the player uses the Diddy Kong amiibo. His unique ability is grabbing any platform's ledge that can be located below the cliff or platform he has fallen from, climb up, and move on from the ledge he grabbed.
