 Costumed actors impersonating Hanna-Barbera cartoon characters such as Yogi Bear, Huckleberry Hound and Snagglepuss (all voiced by Daws Butler) made cameo appearances.Honey and Sis were designed by Hanna-Barbera animator Iwao Takamoto and their costumes created by fashion designer Bob Mackie.They were manipulated by a team of six puppeteers who would wear full-body blue leotards in front of a blue screen, so that the two characters would be chroma-keyed on a different background.
