Mamu

Mamu is a large singing toad who lives in a pond under the Signpost Maze in The Legend of Zelda: Link's Awakening. He is the same character as Wart, the main villain of Yume Kōjō: Doki Doki Panic and its American localization, Super Mario Bros. 2, whose Japanese name is Mamu. The Nintendo Switch remake of The Legend of Zelda: Link's Awakening'' is the first game where Mamu is 3D-modeled.

Unlike his debut appearance, Mamu is not a villain in The Legend of Zelda: Link's Awakening. Link can find Mamu's location by following and reading the signposts in a certain order, causing the stairway to Mamu's home to appear. There, Link can pay 300 rupees for Mamu and his choir to perform a "previously unreleased cut". This teaches Link how to play the Frog's Song of Soul on his Ocarina. After this, Mamu does not reappear, and a signpost outside his home reads that he has gone touring.

Although Mamu does not appear in Hyrule Warriors and Hyrule Warriors Legends, his status as a villain is referenced as a costume for Ganondorf in the Link's Awakening Pack.
