Can I Bring Woolly to the Library, Ms. Reeder?

This laugh-out-loud misadventure is perfect for persistent prehistoric pedants and those who have their heart set on a new pet. 
Once upon a time there was a boy who presented a well-thought out proposal for his teacher, Ms. Johnson, convincing her that bringing a pterodactyl to school would be a good idea. The boy is back, and this time he has several reasons why bringing a woolly mammoth to the library would be advantageous to the librarian, Ms. Reeder, and the library’s patrons. There''s never been a better shelving assistant, storytime buddy, or bookmobile tower than a woolly mammoth! What could possibly go wrong?
