Gameplay
This event starts with the characters preparing to dive into the pool on the starting platform. Once "Ready?" appears on screen, the player can touch and hold the Action Button to charge up energy for their initial dive. The longer the player charges for, the faster their dive and starting swimming speed will be. Once "Go!" appears, the player must release the Action Button to dive into the water and start swimming. Doing so with perfect timing will give them a Rocket Start, causing the character to gain a large speed boost for a short amount of time. Once the character starts swimming, the player must draw circles within the marker on the Touch Screen to cause their character to swim. The faster they draw the circles, the faster the character swims, as indicated by the stamina meter. If the meter is filled, a five second countdown begins, and if the player does not slow don enough during this time, the character will stop and lose all of their speed. As the character approaches the end of the pool, the player will be prompted to turn around by pressing the Action Button when the line touches the wall. They will be rated on their timing and will gain a speed boost depending on how good their timing was. If they fail to turn around, the character will lose all of their speed. As the player approaches the finish line on the second length, they are able to perform a Super Swim which gives them a short speed boost with a unique character effect. This can only be used once in the event.

Advice
