 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.Although only scheduled for a five-week test run, "The Hanna-Barbera Happy Hour" failed in the ratings as it competed with ABC's "Welcome Back, Kotter" and "What's Happening!!"
