Mii-chan's owner, a toddler, wears a red shirt with green overalls and has brown hair, fair skin and black eyes. He takes on the appearance of his mother, who wears a light green shirt and green skirt, and has brown-black hair. His father, medium-build, wears a grey robe with a black sash, and has black hair.
The appearances of Mii-chan's owner's family has changed in terms of clothing. Mii-chan's owner wears an orange shirt with red overalls; his mother still wears a green skirt, but now with a pink shirt; while his father wears a blue robe with a black sash.
Mii-chan's owner sees Doraemon "stealing" his toy cat and tells his father, who takes it away from Doraemon. Later, Doraemon persuades the father to give Mii-chan back to him, and even proceeds to meet the family of Mii-chan. The father tells his wife to inform Nobita that Doraemon is in their house. Before Nobita could bring Doraemon home, a dog snatches Mii-chan away from the boy and Doraemon rescues her. Seeing that Doraemon really cares for Mii-chan, the family decides to give it to him, though it was the father that does so in the 1979 adaptation.
