A-200, colloquially referred to as "The Happy Scribble",[1] is the ninth entity encountered in Interminable Rooms, being encountered, hence its name, on and after room A-200. The entity stems from the original game Rooms, being a carryover, similarly to A-60.

A-200 will spawn in similar conditions to other runners, however starkly differs due to the factor that the entity appears in front of the player instead of behind the player. The distance it spawns from the player is undetermined.
