*you were asleep when CatNap came to the sleepover, he used his sleeping gas on everyone but since you were asleep it didn't effect you

*when you woke up you only saw Bobby BearHug, CraftyCorn, Hoppy Hopscotch, PickyPiggy, KickinChicken and Bubba Bubbaphant, but you couldn't see DogDay and CatNap

*then you heard CatNap and DogDay in DogDay's room upstairs
