When Deliria shapeshifts into a sickly looking plant to avoid a citation, Wizzy and Wigg take "the plant" to Headquarters to take care of it. To better understand their new responsibility, the older Zpers teach the youngsters the qualities of living things (and the difference between a plant and an animal). Wizzy and Wigg decide to study "the plant", to figure out how a plant makes its food. However Deliria isn't a plant, so she doesn't respond like the others. It isn't long before the curious duo deduce that their "plant" is really an animal. The Zula Patrol returns to Itty-Bitty City to settle a crisis when Mayor Paula Paramecium splits in two and neither twin is willing to relinquish office.
