Teenage Kirby dreams of becoming a famous animator like his idol, Mac MacCallister. That may be why he is joined on his adventures by a variety of animated characters - each with a distinctly vibrant personality - which only he can see. Adventures take him all around his unusual town, Forest Hills, with best friends Fish and Eli. The threesome usually get into some predicament that they must escape before Kirby's crafty older sister, Dawn, and her whip-smart best friend, Belinda, catch them.
