In the wake of the Great Mushroom War and the vampire infestation, the remaining humans of Ooo have set sail for safer shores. Bunny Girl (aka Jo) is fearful of what dangers await them. Luckily, they soon reach a plentiful island populated by another gregarious group of humans and attempt to build a new colony. Disaster strikes, however, and separated from her tribe, Jo must brave the dangers of the wild to get back home.
