Christmas Melmo
One night while she is counting the days to Christmas on her fingers, Melmo finds an abandoned child. She gives a candy to the child to make him grow up to be a boy, and finds out that the child is named Tadao and was abandoned by his parents who had lost their jobs. Melmo then turns the president, who abandoned Tadao's father, into an old man. The president apologizes in a fit of tears, and he promises that he will by all means find Tadao's parents and take care of them. In the meantime, Tadao's parents are heading for a snowy mountain to commit suicide. Source: tezukaosamu.net

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.
