Boy, nobody even tried a guess on this one! In the 50's and 60's comic books often had 2 stories, the main one with the most popular character, such as Donald Duck, Mickey Mouse, etc. and a secondary one. One of my favorites of this latter group was "Mary Jane and Sniffles". Sniffles was a mouse, Mary's Jane a little girl. If Mary Jane said, "Magic words of poof, poof, piffles, Makes me just as small as Sniffles!" she would shrink down to the mouse's size and they would go on all kinds of adventures.
