Trunker

Trunker is a tree that appears in Gobi's Valley on the island in front of the start. He is very thirsty and needs water. You need to find Gobi and free him then come back to Trunker's island and use the Beak Buster on Gobi's back to water Trunker. After this, Gobi will leave and Trunker will grow and reveal a Jiggy on his head. You can get this Jiggy by either flying to it or climbing the nearest palm tree and doing the Feathery Flap to get over to Trunker.
