Satan's Christmas Grotto

Many places have a "Christmas Grotto" complete with the usual fake snow, people dressed as elves, fairy lights and of course a person portraying Santa Claus in the "traditional" red-and-white costume.

This can actually be quite an overwhelming and traumatic experience for kids, particularly small ones - so a damp lap is an occupational hazard for Santas, and many children are unable to speak above a whisper, verbalize their desires for presents, or even speak at all.

Now ...

Apparently, some children go through a developmental phase called the "Terrible Twos" which can be a right nuisance for the parents and everyone else in their vicinity. But they are also quite impressionable at that age, too ...

So, we are developing a concept for an add-on to the conventional grotto. Having been to see Santa, the victim exits through a different door (which slams shut behind them with an ominous crash) from the one they entered by, and finds themselves in Satan's grotto, complete with pitchfork-equipped demons, smoke and sulphur, lakes of fire, torture implements, and Old Nick himself - who proceeds to tell the cowering child that they if they're ever naughty again, not only will they get no Christmas presents, but will eventually end up back in the Infernal Regions for all eternity, suffering unbearable torment.

The terrified customer is then chased out of the exit by the demons, consoled by its parents, and then taken home.

Works best on Catholics.
