Like Doozers, they clean up detritus and teach Creatures new words when pushed. Unlike Doozers, however, they prefer living in the water to dry land. While a regular Doozer will scream and bounce around when it falls in the water, Water Doozies display this behavior out of water. Unfortunately this only makes it more difficult to return them to the water, and often the easiest way to "rescue" them is simpy to remove and then reinject them.
Water Doozies can be found at Adventures in Nornsitting.
