Mo Willems does more than just write best-selling childrens books. He’s also a cook — well, according to this trailer for his latest Elephant & Piggie book, I Really Like Slop! But before you praise his culinary skills, take note: He’s cooking “slop,” which is made from a stinky shoe, old cream cheese, marbles, and more.

Check out the looks on these kids’ faces when Willems shows them what they’ll be “eating,” above. And below, preview some interiors from I Really Like Slop! before the book hits stores on Oct. 27.
