Stanley in “Stanley's Great Big Book of Adventure”

[Stanley knocks at Lionel's door and peeks into his room. Lionel's chair has been turned over, and Stanley's open book lying on the floor, next to it.]

Lionel? Lionel? Lionel! Are you here? [goes into Lionel's room and spots his book] Hey, my book! I'm taking my book back, Lionel! [no answer] That's weird.

[Stanley props Lionel's chair back up and looks into his book.]

What's that? [he sees a picture of Lionel's headphones in the snow] Those are Lionel's headphones. What are Lionel's headphones doing in--[horrified] Oh, no! Lionel fell into the Great Big Book of Everything!
