Hollowback – Abandoned Amusement Park Creature Concept

A jester-like anomaly that appears human from a distance.
When seen from behind, its upper body is revealed to be hollow, exposing its inhuman nature.
It is often found lingering around abandoned kiosks and photo spots within deserted amusement parks.
Despite the presence of humans, it shows no reaction, though it has occasionally been observed carrying balloons used for balloon art.
