Completing all the stunts and passing through all the rings in a Stunt-mode run of Dolphin Park will cause some dolphin noises to play as the player crosses the finish line, and all the characters on the title screen will then be riding dolphins. This will also enable the player to ride a dolphin in Dolphin Park in the the Normal difficulty Championship mode, by holding Down on the D-Pad or Control Stick while selecting a rider.

In the Virtual Console rerelease, all the in-game advertisements for Kawasaki and Fanta were changed to Wii and DS Lite banners, most likely due to the product licenses having expired.
