Lost child locator

Sammy couldn't decide between the waltzer and the fun house, but eventually settled for the former. Waiting in the queue with his dad, his eyes kept flitting back over to the candy floss stall, bedecked in bright, pink candy floss. He could almost smell it. Almost unthinkingly his feet moved one in front of the other, carrying him towards the swollen bags of spun sugar hanging from the stall front. He was standing under the bags, looking up wide-eyed. He would need money. From his dad. Where had he left his dad? There were hundreds of people around, but he couldn't see his dad or the fun house. He could feel the panic rising with the tears. But wait! Sammy remembered his emergency kit on his wrist.

Pulling back his sleeve he revealed a small cylinder on a wristband with a red toggle on one end. He pulled the toggle and a red balloon inflated itself from the far end, revealing the words "Sammy is here!". When fully inflated it detached itself from the wristband and rose slowly into the air, pulling a twenty foot line of cotton out after it that tethered it to his wrist. Sammy stood calmly under the gently bobbing balloon and waited to help to come.
