Mini Spek

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 minis in the game, Mini Speks do not have any special abilities beyond what minis are capable of in previous games in the Mario vs. Donkey Kong series.

For some reason, despite being a Mario character, using Wario's amiibo in this game will only lead to the player using a Mini Spek, as there is no toy based on Wario in this game.
