"Somebody Has Been Sitting In My Chair!"

and the Little Bear piped:

"Somebody has been sitting in my chair, and has broken it all to pieces!"

So they went upstairs into the chamber, and the Big Bear growled:

"SOMEBODY HAS BEEN TUMBLING MY BED!"

and the Middle-sized Bear said:

"Somebody Has Been Tumbling My Bed!"

and the little Bear piped:

"Somebody has been tumbling my bed, and here she is!"

At that, Silver-hair woke in a fright, and jumped out of the window and ran away as fast as her legs could carry her, and never went near the Three Bears' snug little house again.
