Dimitri

From Zelda Wiki.org

Dimitri is one of three animal companions that you can get in Oracle of Ages and Oracle of Seasons (the other two are Ricky and Moosh). Dimitri is a friendly, red Dodongo. Link befriends him after saving him from a group of rather nasty children. He can swim up waterfalls and through currents without being pulled along. If you press A when riding him, he will bite and eat enemies. You can also pick him up and throw him with the Power Bracelet when you are not riding him. Use Dimitri's Flute to call him.
