Annoying Popups? You bet!

They/Them/It/Its

They have multiple jack-in-the-box style boxes all around the place, and can pop out of any of them by entering one. Nobody knows what is actually inside the box, though some speculate that it's some sort of pocket dimension.

They'll try to sell goods to pretty much anyone who walks by one of their boxes. They can be a bit... pushy when it comes to sales, repeatedly asking people if they're sure they don't want to buy anything, until they eventually just walk off.

Has never been seen outside their boxes.
