This bright, brilliant, and drily humorous new picture book is the perfect go-to guide for going Number Two.

Someone has done business where they’re not supposed to. But who was it?

Suspense builds as suspects are rhythmically, methodically eliminated. We know it wasn’t the baby (diaper), or Daddy (bathroom), or the lion at the zoo (too risky).

There’s a place for everything, and Shawn Harris’s snappy text and stylish, accessible art shine in this universal, hilarious, and perfectly paced picture book about the right place for bathroom business.
