NPCs will often comment on Unpleasant staring at them in a creepy way despite their lack of eyes or a face. NPCs will also usually point out that Unpleasant smells extremely bad.

Unpleasant has a random chance to come out from Infected's room in the Infected Apartment floor and slowly walk to the elevator. Once it enters the elevator, the SpongeBob "boowomp" sound effect will play.
