Hippos should not eat rocks.

From Kiss Kiss by Margaret Wild and Bridget Strevens-Marzo.  A great present with a
purple hippo Pillow Pet who likes to obnoxiously
kiss little kids while you read them a book.

During Audrey's bedtime story, Kiss Kiss, Sebastian noticed something amiss with the Mama Hippo calling out to Baby Hippo:

"Mom, why is that hippo eating a rock?"

"She's not, Bud, she's turning to call out and that's her back."

"No, she's eating a rock. She should not eat a rock. That is disGUSting. That is a BAD CHOICE. I don't want her to eat the rock. That is a BIG rock. She should not eat that disgusting rock, Mom..."

Audrey was so captivated by his version of the story and it was so far after bedtime, I closed the book, handed it over to him, got up, left the room, and turned off the light before he even took a breath.

Illustrators of the world: I'll need this picture in every bedtime story from here on. Thanks in advance.
