Mary Had a Little Dagnaserub

A very short children's science fiction story:
Seven year old Mary Johnson met up with a little creature that lost his spaceship. She just thought it was a cute little animal she could take home as a secret pet. Secret because grandma doesn't want pets in her house. When she realized who and what he really was she helped him retrieve his ship so he could return to his mother ship and from there to his home world in the stars.
