I'm SorryHardcover, 7 September 2021

In this fourth book in the series from New York Times bestselling author Michael Ian Black and celebrated illustrator Debbie Ridpath Ohi, a flamingo and a very sorry potato learn how to mend hurt feelings.

Flamingo is upset. Very upset.

Potato is sorry. Very sorry. In fact, he is the sorriest.

But he doesn't know how to tell Flamingo. He would rather run away to the South Pole and live with penguins. He'd rather wear a disguise for the rest of time. But will that be enough to fix their friendship? Will they ever go back to being a girl, a potato, and a flamingo again?
