Krampus

A large, horned, demonic figure with a long tongue and a chain weapon stands in a snowy, dark environment, its form revealed as the camera pulls back to show two small, frightened children in the foreground. The scene is a stop-motion animation where the camera slowly zooms out, first focusing on the creature's lower body and weapons, then revealing its full monstrous form, and finally showing the children's terrified reactions as they look up at it.
