The New York Times-bestselling children's book series returns with The Pout-Pout Fish and the Mad, Mad Day.

The Pout-Pout Fish's morning has been maddening and rough. Disappointments and frustrations--Mr. Fish has had enough! It's been one thing, then another, then another stacked on top. He's mad and getting madder. Is there any way to stop?

Swim along with Mr. Fish as he faces his anger and gains new understandings. With a little help from his friends, he might just discover the healing power of words and self-compassion.
