Delfy is a very strict protector of the seas. He always keeps a look out whether the sea is clean or whether the sea is harmed by the notorious Captain Vinager and his assistant Boing the Kangaroo. Captain Vingear is most likely notorious in trying to stop Delfy from protecting the seas from danger. And best of all, he protects the Baby Whale from being eating by the sharks named Sharky and Sharko.
