Going After Guppy
Mario starts on a small piece of land holding the Toad Brigade captain and several penguins complaining about Guppy. In order to get things going, the player must confront Guppy, in which he challenges you to see who has the better flippers by having you go through all eight rings that he sets. Each ring has its own time limit. If the player fails to go through the ring in time, you lose a life, and must start over again. Once you have gone through all eight rings, Guppy sticks to his word, and gives you a Power Star.

Underwater Cosmic Mario Race
Mario starts of on an island. After taking a few steps Cosmic Mario will appear and then the race starts. As the name of the mission states, the player must jump into the water and race Cosmic Mario to the Star. The trick is to do a Long Jump into the water and grab a Red Shell once your in the water. Halfway through the race Cosmic Mario will jump out into another small island. This is a chance to catch up and get the star. If you fail to get the star you will lose a life and have to start again.
