Cartoon Network Summer during the CN City era (especially 2005 and 2006) was defined by a large, city-wide party theme, featuring a special outdoor stage and music. It served as a platform to debut new original series, such as The Life & Times of Juniper Lee, Camp Lazlo, and Squirrel Boy. It introduced a specific visual style with animated bumpers featuring characters interacting within the 3D "CN City" universe. This summer event was characterized by a festive atmosphere and a marketing push around the CN City branding.
