Moosh is a character who appears in Oracle of Ages and Oracle of Seasons. He is a blue bear with the power of flight; this ability allows Link to be able to fly over pits when riding him. However, Moosh cannot fly forever and eventually needs to lands; he also cannot fly over water since he is afraid of it. He also has a ground smash attack.
Oracle of Ages
Moosh is the first of three animal companions who Link must help along his journey. Link first meets Moosh in the Yoll Graveyard while going to retrieve the Cheval Rope and Flippers from Cheval's Tomb. After being saved from a group of Octoroks, Moosh will help Link to fly over the holes leading to Cheval's grave. When the Flippers and Cheval Rope are obtained, Moosh will leave.
Moosh has the ability to fly over a longer string of area than Link can simply jump over, which becomes especially useful when having to cross a path filled with holes in the ground. As an attack, he can also use the Ground Pound technique, where he will charge power while hovering over an enemy (or group of enemies), then release it by powerfully crashing to the ground. One downside to Moosh is that he cannot swim and will sink into any deep water that Link take him in.
If Link does not gather a Strange Flute anywhere else throughout his adventure before entering the Nuun Highlands, then he will encounter Moosh for a second time in the Fairies' Woods. There, the Fairies will inform Link that Moosh has gotten lost within the woods and needs help finding his way out. After helping Moosh for a second time, he will give Link his Moosh's Flute, which allows him to be called upon almost anywhere in the overworld and as frequently as needed.
Oracle of Seasons
Moosh can be found while Link is exploring Mt. Cucco. Moosh asks Link to get the Spring Bananas that are atop of Mt. Cucco for him. After Link does this Moosh will help Link on his quest to find the key to the Dancing Dragon Dungeon.
If Link has purchased a Strange Flute from the shop after the second dungeon Moosh will join him at Spool Swamp after Link saves him from Moblins, Moosh will turn the Strange Flute into Moosh's Flute.
