Dirt Boss

The Dirt Boss is a giant mole awoken by Gedatsu during his work for Goro. At first, the Dirt Boss attacks Gedatsu, but he's easily defeated and becomes a subordinate of the former priest of Enel. He helps Goro and Gedatsu in finding water underground, and then digs 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.
