Cartoon about girl and boy on island with pet dolphin?
I am looking for the title of a c artoon from the 80s or 70s maybe earleier. I have only vague memories, but I know there was a little girl with red-hair and she didn't wear a shirt, m and her brother lived there also, and a father figure of some sort. They fished in the ocean and there was a pet sloth and I think a pet bird and eventually the kids befriended a dolphin that was hurt. They built a tide pool for the dolphin to hang out in while it recovered. I remember thae little girl chanting "i;ve got a dolphin, i've got a dolphin!" the dolphin had a run-in with some killer whales and in the end there was a tugboat and a helicopter... a killer whale baby swam into a grotto and the boy and/or the dolphin rescued it... I can't find info on this cartoon anywhere!! Help me!!
