Surf

Surf is adventurous, and wild. He is scared of the land, and he never comes out of the water. This is mysterious to his tribe.

But, it actually comes from the traumatic loss of his crush, Clam. Clam was attacked by a wave of seabirds, and was killed. Surf blames Clam's best friend, Seagull who brought her to the land.

So, Surf kills Seagull, and tells his tribe that she is just gone on a mission. The tribe still is waiting for Seagull to return.
