An Orca Named Beluga

Beluga is an orca with a very confusing name. Is he a beluga or an orca? Nobody seems to know! Beluga has been searching all over the ocean for a friend to play with, but with such a perplexing name, none of the other sea creatures seem to know what to make of the poor orca.... until one day when he meets a dolphin with a confusing problem of his own.
