0:00 The biggest closet in the world is in a castle in England and it's two hundred feet long.0:08 Last week, we heard a strange tap-tap at the window, but this week, the mystery is much closer.0:17 It’s coming from inside a closet that’s probably… just your size.0:24 Alex was tucked in tight.0:26 The moon was a bright silver coin outside the window, painting stripes on the bedroom floor.0:35 The house was quiet.0:37 So quiet you could hear the soft hum of the refrigerator all the way downstairs.0:45 It was the perfect kind of quiet for sleeping.0:49 Until it wasn't.0:51 Thump.0:52 Thump.0:52 Alex’s eyes popped open.0:55 What was that?0:56 It wasn’t a loud sound.0:58 It was soft, like a pillow falling on the floor.1:03 Thump.1:03 Thump.1:04 It stopped.1:05 Alex held very still, listening with ears wide open.1:10 Maybe it was just the house settling.1:14 Old houses make funny noises.1:17 But then… it came again.1:19 Thump… thump.1:20 And this time, Alex knew exactly where it was coming from.1:26 The closet.1:27 The closet door was open just a crack.1:31 A dark, skinny line in the moonlit room.1:35 Alex’s heart started to beat a little faster.1:39 A little pitter-patter.1:41 Almost like the sound.1:43 Thump-thump.1:45 Should Alex hide under the covers?1:48 Should Alex call for Mom or Dad?1:51 No.1:51 Alex decided to be brave.1:54 Slowly, one leg at a time, Alex slid out from the warm blankets.2:00 The floor was cold on bare feet.2:03 Tiptoe… tiptoe… across the stripes of moonlight.2:08 Right up to the closet door.2:10 The thumping had stopped again.2:13 It was waiting.2:15 Alex put a hand on the cool wood of the door and… pushed.2:21 The door swung open with a tiny creak.2:24 The sound started again, right away.2:28 Thump… thump.2:29 It was coming from the floor, in the back corner, behind the winter coats.2:36 Alex reached up, feeling for the little string that turned on the closet light.2:44 Fingers found it.2:46 Alex took a deep breath, and pulled.2:49 Click!2:50 The small lightbulb flickered on.2:53 And there, in the corner, was a single red rain boot.2:58 And every time the house gently rumbled from the furnace kicking on downstairs, the boot would wobble just a tiny bit.3:10 And inside the boot, a lost tennis ball would gently knock against the side.3:17 Thump… thump.3:18 It wasn’t a monster.3:20 It wasn’t a ghost.3:22 It was a bouncy ball, trapped in a boot, playing a tiny little drum solo all by itself.3:30 Alex reached in, tipped the boot over, and the tennis ball rolled out with a final, soft… thump.3:40 The closet was quiet again.3:42 Alex picked up the ball, put it in the toy box where it belonged, and climbed back into bed.3:51 The sheets felt even warmer now.3:55 The room was perfectly quiet.3:57 And Alex smiled in the dark, knowing that even mysterious sounds can have very silly secrets.
