Monobeast

The monobeast is a vermin which detaches from a Patient suffering from Monobrow. It then moves independently throughout your hospital. When you mouse over a monobeast, the cursor becomes a targeting reticule. You may then exterminate the monobeast, so that a Janitor may dispose of its remains. You must have at least one Janitor in the hospital in order to shoot them. They also cannot be shot while the game is paused or in slow speed.

Monobeast cause no ill effect to a hospital, however once they have been shot they leave an unhygienic mess. Once they detach from the patients forehead they will run and hide under items around the hospital. Monoboeast are especially fond of warm radiators. Picking up the item will cause the Monobeast to run and find a new location.

Other popular places to hide include anything involving food, such as vending machines and bins, large items such as the reception desk but the most attractive home is the Browbeater.

Monobeast will not go into rooms, they will remain in corridors only.

Browbeater
In The Superbug Initiative there is a Hair Removal project that rewards the Browbeater item. These can placed in hospital to attract and trap monobeasts humanely.

Trivia

 * Shooting monobeasts is a reference to Two-Point Hospital's spiritual predecessor, Theme Hospital. In Theme Hospital, you could shoot rats that infested your hospital when hygiene became too low.
