The map appeared one morning, folded neatly on the porch with no name on it. It was covered in tiny X's and looping arrows and one very serious note: 'Mini-Missions Inside.'
The Zoo set off together. They followed the map past the pond, around the old oak, under the bridge that wasn't really a bridge — and the more they wandered, the more they laughed.
When they reached the final X, there was nothing there. Just a clearing, and the sun, and each other.
The Zookeeper smiled. 'I think,' they said, 'this map was never about where we were going. It was about who we were going with.'
