Since the toyline never gave names for much of the characters aside from Ricky, the development team (consisting of Jean Chapolin, J. Michael Straczynski, Terrence McDonnell, Phil Mendez and Alan Swayze) created distinct names and personalities for the characters.
Several episodes of the series were released under Karl-Lorimar's "Kideo Video" branding on VHS in the 1980s, with two episodes per tape.
IGN gave the show a honorable mention in their Top 100 Animated Series list.
