Poop!

Barefoot Books released this board book in its Slide-and-See line, which centers on STEM subjects. Its topic is poop, a subject many children find irresistible, and it is designed to spark early scientific curiosity.

Each riddle describes the droppings of a different creature, and readers try to work out which animal left each one. The picture changes when the page is turned, revealing the answer and keeping the guessing game moving along.

The closing pages add a set of notes packed with facts about the waste produced by different animals.
