Foggy mornings are better spent playing inside, and this particular foggy day Luna, Jupiter, and Clyde are having fun taking care of Luna’s pet snail, Shelly. While playing with their mollusk friend, Jupiter suddenly sneezes one of those great big dramatic sneezes, sending Shelly back into her shell for cover. As they wait for her to come back out, they start wondering what it might be like in Shelly’s house. Does she have a TV? Maybe some video games? It’s time for the trio to become snails themselves and find out just what goes on inside a snail’s shell.
