The story begins with Oliver's mom passing away. Understandably distraught, the boy begins to cry on top of a strange stuffed animal left to him by his mother. The sorrowful tears magically bring the doll to life, who soon introduces himself as Mr. Drippy, a long-nosed creature with a lantern inserted awkwardly through his septum. Drippy informs Oliver that there's another world out there where all humans and animals have analog selves. The idea is that because there is "another" version of his late mom somewhere over the rainbow, a quick journey to the other side might just provide a solution to bringing her back. Oliver and Mr. Drippy embark, and the adventure begins.
