They all play a pivotal role, but the Deku shell is too light in most cases, while the Goron shell is specifically used to press down switches that are bigger than usual. The shells can only be formed if Link is in any of the areas pertaining to Ikana Canyon; if the song is played anywhere else, it will not have any effect. The shells that Link's Deku, Goron, and Zora form leave are that of Deku Butler's Son, Darmani III, and Mikau, respectively.
