Partygoers are bipedal, smart humanoids made of yellow fabric.

Partygoers have no facial features except a red cartoony "smile" carved into their "faces" as seen in the pictures above.

Partygoers are very smart and have advanzed knowledge of no-clipping  and engineering.

Partygoers can No-clip at will to where they want to as well as operating complicated machinery on hard and dangerous levels. they can also use their knowledge of No-clipping to set up traps like windows with confetti coming out of it on level 188 or Walls that lead to Level fun, and purple slides with trap messages like "Escape!" or "Come and join the party"

The main habitat of Partygoers is Level FUN, but can also be encountered on trap levels like The End, or infested levels 

like LEVEL !: RUN!!!!!!!

although Partygoers can no-clip at will, theyre pretty slow while traveling through normal methods like walking or running, thats why they prefer to use No-clipping instead to both travel to other levels and teleport within the level  to hunt prey. they usualy hunt in packs. Partygoers are the main enemy of The Partypoopers, friendly entities that reside in level 52: The School Halls. The Partygoers usually carry red balloons on their hands but can also be free.
