Lost thing

A boy discovers a bizarre-looking creature while out collecting bottle-tops at a beach. Having guessed that it is lost, he tries to find out who owns it or where it belongs, but the problem is met with indifference by everyone else, who barely notices its presence. Each is unhelpful in their own way; strangers, friends, parents are all unwilling to entertain this uninvited interruption to day-to-day life. In spite of his better judgement, the boy feels sorry for this hapless creature, and attempts to find out where it belongs.
