Bagu is the strongest man in the whole of Hyrule. He lives in a small house in the woods north of Saria, kept company by his two beloved frogs, Langhorn and Calaveras.He also has a pet bot, which resides in his house in the town of Saria. When Link wanted to cross the river in Saria in order to reach Death Mountain, it was Bagu who gave him permission so that the guards would let him go over the bridge. They became friends after that, but later on, he stole the Triforce of Wisdom for Ganon, in order to get his frogs back, which the wizard had cruelly stolen. Link realised that Bagu had not meant to do it, but he just wanted his beloved pets to be safe.

On the Day of the Triforce (a day which occurs once a decade, where the Triforces power is lost), Lynels burned the village down.
