The cartoon follows the lives of three animal roommates who live in a stump. There's Pickle, the wild, playful rabbit who's always up for an adventure (voice of Tabitha St. Germain). There's Gull, the simple-minded but friendly seagull (voice of Lee Tockar). And finally, there's Merl, the high-strung chipmunk who acts as the Straight Man of the trio (voice of Samuel Vincent).
The cartoon was released on Teletoon on March 3rd, 2015. It ran for only a single season of 26 episodes and came to an end rather swiftly on June 2 of the same year. It also aired on CBBC in the United Kingdom.
