The Lost Thing (2010)

A boy discovers a bizarre looking creature while out collecting bottle tops at the beach. Having guessed it is lost, he tries to find its owner or where it belongs, but is met with mute indifference from everyone else, who barely notice its presence, each unwilling to entertain this interruption to their daily lives. For reasons he does not explain, the boy empathises with the creature, and sets out to find a 'place' for it.
