This was the 13th Winglet and the first time the CheeseWings were introduced. This particular book is unique, because unlike any of the other winglets, there is no POV character, just Clay's thoughts.
After Clay gets lost on a date with his watermelon Sally, he comes to Cheese World. There, he meets Queen Mozzarella, and is given a tour by her. The queen lets him eat all the cheese he wants. He is in paradise, eating all the cheese he can. Then he accidentally eats Dirtbag, Queen Mozzarella's cow. Queen Mozzarella gets mad and shoots him with her hot cheese breath. It turns out Clay is immune, though, and easily escapes. However, the queen gets stuck in quickcheese and has to be pulled out by her subjects.
