Carben

Carben is a character from Spirit Tracks. He is a member of the Lokomo race and guardian of the Ocean Realm.

On the trip to meet him, it is revealed that he went to Papuchia Village. Once Link goes there to find him, he learns the Song of Birds. Carben agrees to aid Link on the condition that Link gives him a ride back to the Ocean Sanctuary on the Spirit Train. On the way, Link and Carben are attacked by Pirates and Link must fend them off. After Link defeats them, Carben will give Link a Force Gem that extends the rails in the Forest Realm and he will proceed to the Ocean Sanctuary where he will perform the Lokomo song.
