The Zimwi is a legendary creature that roams the Pride Lands on the night of the full moon. When Rafiki tells a group of young animals a story about the Zimwi, the young ones inadvertently spread false rumors that the creature has been seen in the Pride Lands. The Lion Guard sets out to put a stop to the beast, but their fear leads them to mistake two young porcupines for the Zimwi. The matter is soon cleared up, and the Lion Guard realizes that the Zimwi was never truly a danger to them.
