The Water Dojo was a treacherous dojo, located behind the large waterfall in the mountains of Club Penguin Island. Here, the ancient art of Card-Jitsu Water was practiced by penguins. The dojo itself was positioned on a large chunk of mossy rock, supported by chains. There were a series of streams that poured down from above onto the floor of the Water Dojo, which then were poured deep down by two small waterfalls in the corners of the dojo. There were two statues of Water Ninjas, and a raised platform where Sensei resided.
