Just kidding, that game was impossible... I don't think I even realized I was a dolphin until 5 days after I gave up and was like "Hah... I was a dolphin".
If anyone still has that game they should go to gamefaqs and actually figure out how to beat it. That game bugged me for months before I gave up and went on a dolphin killing spree. I'm still the most wanted man at Seaworld.
