The Partypooper, a melancholic and solitary figure, roams the Backrooms with a demeanor that deters others. While his presence may seem dismal, he provides an invaluable service by keeping other entities at bay. Distinct from the exuberant Partygoers, the Partypooper is often shunned for his lack of enthusiasm and cheer. In the Backrooms, the Partypooper companion enables you to cover Entities below Purple Rarity with Room Cards, effectively concealing them. His sorrowful presence acts as a deterrent, as other entities avoid him, much like avoiding a raincloud at a picnic. However, should he glimpse a Painite Gem in the possession of a companion, he interprets this as a sign of impending abandonment. Viewing the gem as an omen, he will promptly flee to seek companionship elsewhere, vanishing to the Discard Pile (DP).
