Exactly why I enjoy all episodes! So here, Sakura and her friends spends the whole day at a brand new water park where Sakura is very alert on trying out the waterslide. When she relaxes with her friends, Li and Eli compete in a pool to try and beat the other's fastest lap time. However as the day goes on, things turn a little intense when the wave machine goes berserk, causing havoc in a pool. With all of the swimmers trapped in the waves, Sakura finds a place to transform the Watery card without being seen and finally does so in the waterslide, successfully transforming the card and taming the waves. A few more cards for her to transform and she'll be master. Overall, I rate this episode a 100%!
