Leopold The See-Through Crumbpicker

Have you ever seen a See-Through Crumbpicker? Well, neither had Minerva! But, one day, eating yummy cookies and dropping lots of crumbs because her front teeth were missing, Leopold the See-Through Crumbpicker brushed by her and ate up all the crumbs. He sounded nice, and he felt warm and furry-so even though she couldn't see him, they became fast friends. What could go wrong?
