Mother Is Back!
A man named Damon visits Melmo's house and tells her that he will let her see her mother if she gave him candies. True to his words, Melmo's mother is back. But Totoo who is now a frog and Touch, who is only a little baby, instinctively understands that the mother is a fake. In fact, the mother who comes back home is a doll that has been implanted with a snake's soul and is being manipulated by Damon. Melmo runs away from the fake mother, but the mother with a snake's soul begins to truly love Melmo and her little brothers. Source: tezukaosamu.net
Aired 21/11/1971EP 8 - Mother Is Back!
Fushigi na Melmo
After nine-year-old Melmo loses her mother in a car accident, she is left to care for her two younger brothers, a task far beyond her age or means. However, in the midst of her grieving, Melmo is visited by the ghost of her deceased mother who gives her a bottle of miraculous candy, capable of transforming her into either an adult (blue candy) or an infant (red candy). A combination of the two can reduce her to a fetus and then change her into any animal she imagines. Drawing on a seemingly inexhaustable supply, Melmo uses her candies to solve the various problems thrown her way, aided by her younger brother Toto (who accidentally morphs into a frog in episode 7) and her cantankerous mentor, Dr Nosehairs.
