@NickNouse and @ivan321 for most of the coding (I think it was mostly @NickyNouse.. but view @ivan321 and @NickyNouse's projects for details) I deleted the costumes of the killer whale and made a dolphin one (I know it looks pretty horrible lol, but it's kind of cute :P Dolphin costumes by @ExperienceSea
