The Flypaper is an Inventory Item that can be used in the game.
The Flypaper is a long strip of paper covered in very sticky glue. It is usually hung where flies tend to fly in circles. When a fly lands on the Flypaper the fly becomes stuck and cannot escape.
The Flypaper can be found hanging from a high shelf next to the bar in the pub.
Josef can simply extend himself and reach up to collect the Flypaper.
Josef can use the Flypaper to collect some of the Flies that are flying over the vat of green sludge outside the pub.
