Eventually, a dust bunny must grow up and become an adult. Adulthood is distinguished by a kind of haphazard shape. Dust bunnies are very good parents, and the adults usually stay near the younger bunnies. When your dust bunny is very large and doesn't move around much anymore, it has become a grandparent. Dust bunnies usually die soon after reaching this stage.
Dust bunnies in different stages of growth.
Featured in the first picture are toddlers and an adolescent. The second picture shows two adults and, on the far right, a grandparent trying to sneak out of the picture. There are little fetuses all around. Very little is actually known about the reproduction of dust bunnies. It is thought that perhaps, where one dust bunny is, more will just appear.
