One of last weekend’s newest eShop titles hides a bizarre yet terrifying feature.

Santa Tracker already includes some strange highlights such as a make-believe blog by Santa and a snow globe. Additionally, you can also play Christmas songs using your Joy-cons’ HD rumble – but it sounds so frightening that you’ll probably stop after the first time.

Check it out a demonstration below if you dare, courtesy of NintenDaan himself.
