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 who work for Bowser. They only appear in the third Super Mario Kart volume of the Super Mario Kodansha manga.

Despite being Monty Moles, the Choropū Chika Butai more closely resemble Mega Moles wearining mining helmets. Earlier on, in the Table of Contents of the Mario Open Golf volume, one Mega Mole with a mining hat can be seen smoking.

History
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.

Trivia

 * In the Mario Open Golf volume, a Mega Mole with a miner hat can be seen smoking in the Table of Contents page. This could mean that, in effect, the Choropū Chika Butai resemble the Mega Mole from that volume.
