Siska opened the box without caution because she was just happy to have received some kind of notice for this ridiculous holiday. However, inside the box was a horrifying sweater with the crude likeness of a jolly polar bear. She winced at it and pulled it on - because she felt bad that someone had gone out of their way to personalize a gift - only to find that it was three sizes too big. The sleeves hung off her hands and it fell to her knees, overall she looked to be drowning in it.
She struggled to take it off only to find herself tangled in it. In her flailing, she mashed a button.
The sweater lit up.
She wailed.
THIS IS HALLOWEEN
