There are other new store items that are just as fun and silly as the toilet-pool, such as a land-shark that's actually a groundhog with a fin tied to its back. Other items head in the direction of just plain fun. How about a surfboard or an obstacle course platform that slides back and forth once placed?
Check out the Free Realms site for all the details on the new goodies, then come on in -- the water's fine!
