Popit is a resident of Riruru Village, hailing from the planet Riruru. He became stranded on Earth following the crash-landing of a spaceship carrying 245 inhabitants, alongside Memole and others. As one of the gnome-like aliens, Popit adapted to life on Earth despite his small size. He sports blue hair, an example of the Otherworldly Technicolour Hair common among Riruru citizens.

Within the village community, Popit is Memole's closest friend. He frequently joins her on adventures, sharing in her explorations and experiences. Their friendship is a steadfast bond; Popit consistently spends time alongside Memole during her activities, serving as her trusted ally in interactions with both the natural world and human characters like Mariel.

Like all Riruru citizens, Popit possesses the ability to communicate with animals. This skill facilitates interactions with local wildlife, including the owl Bo-bo, which the aliens use for transportation. While specific narrative arcs focused solely on Popit are not detailed, his presence contributes to the communal life of the stranded aliens as they navigate coexistence on Earth.
