Does anybody know the name of this Video game classic?

you're being a dolphin who gets washed up on Beachville Beach and has amnesia and a lion walks up to the dolphin who can talk and offers to help the dolphin get his memory back. so Dolphy the dolphin gives leon the lion advice on how to swim and he gives him an astronaut suit so he can go in the ocean. So then they reanacted how dolphy got washed up till they got it right. it took me about 45 times.
