The series focuses on Cricket Green, a mischievous and optimistic country boy who moves to the big city (simply called Big City) with his family. Cricket’s curiosity and enthusiasm leads his wildly out of place family on epic journeys and into the hearts of his new neighbors. Emmy Award-winning director Rob Renzetti (creator of My Life as a Teenage Robot and supervising producer for Gravity Falls) serves as executive producer and the Houghton brothers serve as co-executive producers.

Cricket is the only character who has appeared in every episode of the series.
Cricket and Tilly, however, do not appear in all the shorts.
Tilly was completely absent from "Date Night", whereas she technically does not appear in "Time Crisis" as her imaginary future counterpart appears instead.
