Krampus

And then there's Krampus.

In Central European folklore, Krampus is a horned, anthropomorphic figure described as "half-goat, half-demon", who, during the Christmas season, punishes children who have misbehaved, in contrast with Saint Nicholas, who rewards the well-behaved with gifts.... The origin of the figure is unclear; some folklorists and anthropologists have postulated it as having pre-Christian origins....

Europeans have been exchanging greeting cards featuring Krampus since the 1800s. Sometimes introduced with Gruß vom Krampus (Greetings from Krampus), the cards usually have humorous rhymes and poems. Krampus is often featured looming menacingly over children. He is also shown as having one human foot and one cloven hoof. In some, Krampus has sexual overtones; he is pictured pursuing buxom women. Over time, the representation of Krampus in the cards has changed; older versions have a more frightening Krampus[.]

Maybe your elders weren't so easily frightened.
