Several people have lent their voice for Pebbles, starting with Jean Vander Pyl (Wilma's voice) doing Pebbles as a baby. In this episode the teen Pebbles in the dream sequence was done by Janet Waldo. In a later series, "The Pebbles and Bamm-Bamm Show" Sally Struthers supplied the voice, and in the marriage special "I Yabba Dabba Doo!" the voice of Pebbles was done by Megan Mullally.
