Opposite Day for Dinopotamus (8x10 hardcover)

It's opposite day at Dinopotamus' school. The other kids get easy puzzles, like fill the glass and open the door. The teacher asks Dinopotamus to bring her the big box. What will he do? Dinopotamus is not a typical student.

Opposite day means you get to break rules and disobey instructions.

But only if you get it right. Or maybe you need to get it wrong.
