Voonder and his fellow goblins have a hard time pronouncing the slave's true name, so they simply call him "Tupi".  Tupi is a Tribal Tupinam from the southern jungles.  He, along with many other Tupinam, was captures when slavers raided his village.  Tupi was later sold to Boss Coyote's men and brought to the desert lands where we eventually was purchased by Voonder of the Wilder Clan.

 

Tupi is part of Voonder Stock.
