Bokebonboko

Bokebonboko was the second son of King Pokeportes, a king of Lost Island.

History
At some point in the past, Bokebonboko was born to Pokeportes, king of Lost Island, as the younger brother of Bokehontas. He eventually got a younger brother, named Bokebokepon.

Eventually, Pokeportes told his sons to go find "the tree that grows stars", which he advised was found in the Valley of the Dragons. His sons began the search, with one leaving to the sea, one to the mountain, and one to the forest.

Translation and Dub Issues
In the Odex dub, it's stated that Bokebonboko specifically went to the mountain, while the original Japanese leaves it unclear which son went where.
