Trunker

Trunker is a turban-wearing coconut tree who appears in Gobi's Valley on a small island next to the world's starting point. Trunker tells Banjo and Kazooie that he is very thirsty. Kazooie is unsympathetic, asking, "How's your nuts, bark breath?" and earns a scolding from Banjo. Banjo offers some Feathers and Blue Eggs to aid the tree. However, Trunker tells them that only water can help quench his thirst.

After Banjo and Kazooie find Gobi the camel and free him, Gobi runs to Trunker's island to lie in the tree's shade. He comments that Trunker looks dry but that he, Gobi, needs all his water for himself. However, Gobi can be forced to give up his water if Banjo and Kazooie use the Beak Buster ability on Gobi's back, causing the camel to then spit out his stash of water onto Trunker. Gobi runs away complaining, but Trunker grows tall and reveals a Jiggy on his head. Banjo and Kazooie can reach this Jiggy most easily by climbing the nearest palm tree and using the Feathery Flap to reach Trunker's top. Alternatively, the Jiggy can also be reached by flying.

Trivia
Interestingly, the entrance to Gobi's Valley from Gruntilda's Lair is a tree shaped just like Trunker.
