This one was a right snake-in-a-sack to get down to 221. Apologies for any loss of quality that may have resulted from my struggles.

A ball pool. Of all the places that snapped cable could have dumped them, the recoil had thrown them through a window straight into the JunglePlay ball pool. Thank God. Thank God.

"John! John, what is this?"

Confused by the panic in the detective's voice, John spun, only to see Sherlock on his back, flailing madly at the swirling balls as he utterly failed to stop himself sinking. John couldn't help smirking at the ridiculousness of the man.

"You're such a girl when you're out of your comfort zone, you know that?"

"Am… am not." Sherlock had struggled back to his feet, but seemed unwilling to make any further moves yet.

"It's just a ball pool, Sherlock! Kids play in here."

"And their parents let them?"

Sherlock gasped as another ball took his foot from under him and the undulating mass claimed him again.

John would later admit that what he did next was cruel. But utterly, completely worth it.

With the ease of a professional, he slid beneath the surface of the balls, 'swimming' smoothly towards his prey. He waited until his fingertips were brushing that coat, and then… he pounced.

Sherlock's shrieks were enough to bring Security down on them, who, once convinced they weren't vandals, laughed like a drain as Sherlock stumbled and lurched out of the balls.
