It's December 24th, and you're a poltergeist with a problem. That problem is Mallory, the insufferably cheerful human who lives in your house - yes, YOUR house - along with his cat Snowball. He's decorated everything with gaudy lights, put up a tree, and is probably about to sing carols. Unacceptable.
Your mission: eliminate Mallory before midnight strikes. The catch? You're a poltergeist, not some overpowered deity. Your powers are limited to the subtle and indirect - you'll need to be creative. Direct confrontation is off the table. Where's the fun in that anyway?
A word of caution: you're rather attached to having a roof over your... well, spectral form. Some solutions may have unintended consequences. Choose your chaos wisely.
