Gaganmo is, according to Moe, a giant flying squirrel. He/she appears in Densetsu no Starfy 2, Densetsu no Starfy 3 and Densetsu no Starfy 4. In Densetsu no Starfy 2 and 3, he/she teaches Starfy and Starly how to Glide. He/she usually holds Oden and wears his/her Giant Flying Squirrel Mantle. Gaganmo lost the Oden in Densetsu no Starfy 3 and had his/her Giant Flying Squirrel Mantle damaged by Konk, so Starfy, Starly and Moe have to get new ones.
In Densetsu no Starfy 4, Gaganmo may make a minor appearance as one of the possible enemies on the Tree of Beginning map that can be tapped on the touch screen for Pearls.
