The adventures of Wander, an eternally-optimistic intergalactic traveler and constant do-gooder, and his quick-tempered but loyal steed and best friend, Sylvia. The friendliest face in outer space, Wander journeys across the galaxies to spread good cheer and to help anyone he can — much to his overly pragmatic stallion’s chagrin.
