At some point, the freshwater raftballs development took an odd turn. The decrease in the organisms ability to stick that began with the raftball continued until the stickyball was dry enough to spread to the savanna, and even to a place that its infamous ancestor, the stickyballs, couldn't go: the desert. You'll notice that the stickyballs still keep a bit of the raftballs' almost swarm-like behavior, in which the individual balls crowd together. Stickyballs are often scattered from their positions by the desert winds, which often cause large numbers of stickyballs to fall onto other patches. This is why there many low, rocky places that are filled with layers of dead or dying stickyballs, which make great places for scavengers and detritivores.
