Supporting the band's singers was an ensemble of five young dancers.
Dancers were not in the pilot (1983).
These cast members appeared in background scenes in The P*lace; they also performed choreographed routines and served as backup singers and musicians (pretending to play) during the band's performances.
Generally, the dancers were peripheral to the stories; the plots of the episodes almost never incorporated them.
(In at least one episode, their "drummer", Mario Lopez, taught The Kid to wrestle.)
However, during Season 1 (1984), dancer Wendy Brainard performed as a guest star singer for Corey Hart's "It Ain't Enough" and Donna Summer's "Dim All the Lights" and returned to the show as a guest star playing a dance instructor in season 8 (1992).
In addition, over the years, more than twelve of the dancers were given speaking roles in various episodes.
The longest-running dancer in the "Kids Incorporated" cast was Angella Kaye, who appeared on the show for seven years, from 1986 to 1992.
Other noted KI dancers included recording artist Shanice Wilson ("I Love Your Smile"), actor Mario Lopez ("Saved by the Bell", "Extra"), and Broadway choreographer and dancer Darren Lee.
