Dirt Boss

The Dirt Boss is a giant mole awoken by Gedatsu during his work for Goro. At first, the Dirt Boss attacked Gedatsu, but he was easily defeated and became a subordinate of the former priest of Enel. He helped Goro and Gedatsu in finding water underground, and then dug a tunnel connecting Goro's thermal island to Arabasta.

In the anime, Tonjit's grandson appears riding a mole strictly resembling the Dirt Boss, but no connection between the two is mentioned.

In the game Unlimited Cruise the player can catch moles which look like a small version of the Dirt Boss.
