Step 1: Purchase an amulet from the martial arts catalog if you don't have one already. Then click on the door to the Water Dojo.
Step 2: You are now in the Water Dojo. Talk to Sensei and he will give you the water booster deck. Now, becoming a water ninja is basically the same as Card Jitsu Fire. You have to earn points to get four items.
Now, Card Jitsu water is probably the hardest out of the Card Jitsu games. It's basically a race. When you start a game, you have to be ready to play. Now, when you start, you'll see a waterfall with stones on it with either fire, water or snow on them. The elements on the stones will be different sizes. Your cards scroll to the right at the bottom of your screen. When it starts, there will be stones highlighted green around you. Those are the stones you can jump to. Now, if a stone you can jump to has nothing on it, you can just click on it, and you will jump there. But if a stone has fire on it, you have to click on a water card and then click on the stone. If you use a water card on a snow stone, it won't have any effect. But if you use a water card on a water stone, the water will get bigger. Now, the higher number the card, the more of the element it takes away. A 2 card won't have much effect on a element, but a 12 card will put it out. If you use a power card on a stone, it will also put out some of an element that it puts out, and it will rise some of its element around it. Now, the aim is to get to the gong first. Here's a video to give you a visual guide on how to play it.
Now, when you earn your final item, you can challenge Sensei. If you beat him, you get your water gem to go in your amulet. Congratulations! You're a water ninja!
