A Snug Little Fort

I noticed a mysterious dark slit between the bulky sofa and the wall, so I squeezed straight in! It was wonderfully quiet back there, until my elbow nudged a rogue plastic tennis ball wedged under the baseboard. With a loud grunt, I shoved it with both hands until it rolled out, rolling clear across the carpet into the open room. Squeaking in delight, I discovered that this hidden tunnel makes the ultimate secret stash for all kinds of bouncy rolling things.
