Tontatta Kingdom

The Tontatta Kingdom (トンタッタ王国) is a kingdom underneath Green Bit, and home to the Tontatta Tribe (トンタッタ族), a tribe of dwarves ruled by the king Gancho.

History
The Tontatta Kingdom was first seen when the dwarves knocked out Robin and Usopp and dragged them there. When Robin woke up, she asked the dwarves where she was, and they told her that she was in the Tontatta Kingdom under Green Bit.
