While Santa Binky's particular power set would allow him to eat an effectively unlimited number of Very Naughty List people in one night (during his Christmas Eve rounds), he usually only eats about fifty. Others get bagged up and given to his wife, his assistants, Nice List animals who live near him, and so on.

Some time ago he realized that a certain number of Nice List people very, very much wanted to eat people but were too Nice to do it. (Or too afraid of the justice system in whatever country they live in.) Luckily, there was an obvious fix for this.

The result is Naughty List people waking up Christmas morning, taking one look the person they were given to, and realizing that the last thing they are going to see is a yawn and the last thing they will hear is a long, satisfied belch heard from inside the creature that just ate them.

This arrangement satisfied everyone (except the Very Naughty List people, and their complaints were soon too muffled to make out), but certain people at once realized that it was a perfect way to get rid of someone they disliked. Tie the person up, put on a tag and leave them for some happy predator to consume. It would be assumed that Binky set it up and no one would question it.

Santa Binky does not appreciate this line of thinking at all and doing it guarantees that the one who did it will be the next one to wake up and realize that the last thing they see will be a yawn. In a sense Binky's stomach, and those of all his followers and gift recipients, is a justice system all its own. While we never seem to run out of Very Naughty List people, at least there is a certain amount of churn, so to speak.
