Choropū Chika Butai
The Choropū Chika Butai (チョロプー地下部隊, Monty Mole Underground Unit) are a group of Monty Mole miners that work for Bowser, who appear in the third Super Mario Kart volume of the Super Mario Kodansha manga. Despite being Monty Moles, they more closely resemble Mega Moles with additional mining helmets.
During one of the races, Bowser calls upon the Choropū Chika Butai to sabotage the race to allow him and Wario to win the race. The Choropū Chika Butai alongside some Chargin' Chucks help break a supporting beam to make the track fall apart. However, Mario and Peach are able to use a small supporting pipe to drive on the other side and continue the race. Bowser and Wario on the other hand are stuck on the other side of the road.
