Mini Speks are cubic wind-up toys appearing in Mini Mario & Friends: amiibo Challenge. Mini Speks are spawned when the player uses an amiibo corresponding to a character who does not have a proper Mini Toy in the game. Unlike the other playable Mini Toys in the game, Mini Speks do not have any special abilities beyond what Mini Toys are capable of in the previous Mario vs. Donkey Kong games. There are no amiibo Tokens or amiibo Doors for Mini Spek, so the player can only go up to World-Star 1 if Mini Spek is their only character.
