A grin stretched across Leoโ€™s face as he spotted the bear nestled amongst a pile of old board games. It was Barnaby, his childhood companion, missing an ear and smelling faintly of mothballs. He felt a sudden, irresistible urge to cause a bit of delightful chaos. He imagined the things he could do: Barnaby could be the ringleader of a secret spy mission, the confidant of a rebellious teenager, or the star of a one-bear comedy show.

He bought Barnaby without a second thought, ignoring the skeptical look on his wife, Sarah's, face. He then proceeded to spend the rest of the afternoon building an elaborate cardboard castle in the living room, complete with drawbridges and lookout towers.

"I need your help," he declared to Barnaby, placing him carefully at a castle window. "We're going to defend the kingdom against the evil sock puppets." He started rummaging through a box of old toys, his laughter echoing through the room.
