Sickly Child Grew Up Strong: Only in the remake (the manga and original movie doesn't show), where Miyoko as a child is Delicate and Sickly, to the point where her mother sold her soul in exchange for nursing her health to normal.

What Happened to the Mouse?: She just somehow dissappears in the manga and original anime after petrifying Nobita and Doraemon, and doesn't show up for the rest of the story. The remake averts it, however.
