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 onto epic journeys and into the hearts of his new neighbors. Emmy Award-winning director Rob Renzetti (creator of Nickelodeon's 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.

Big City Greens materialized following the failure of the Houghton Brothers attempt to pitch an animated series based on their comic book Reed Gunther to Amazon. They attempted to pitch it at Disney where it too was not picked up. Disney offered that they pitch another show which was Welcome to Simpleton. When that failed, they came up with Country Club which would transition into becoming Big City Greens.
Among the creative influences for the show, Chris Houghton has mentioned Calvin and Hobbes, Life With Louie, The Simpsons, Family Matters, Tom Sawyer, Malcom in the Middle and numerous others.
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.
The episode title cards appear on items seen throughout the show.
According to the creators, the series is mostly set on weekends, weeknights and vacations such as summer break, which explains why Cricket, Tilly and their friends their age have not been seen attending school yet. 
The show is animated traditionally through pencil, ink and paper, as opposed to other contemporary shows that animate via digital ink.
A punk rock group going by the name Big City Sue-zers, created a mini album titled Earworm that features music based on the show. Chris Houghton provided artwork for the album and vocal samples as Cricket along with Marieve Herington as Tilly.
