Creeper's Lab is comprised of a series of different worlds to play in, and everyone starts out their Creeper's Lab experience in the Lobby.
The Lobby is not a world per se, but the landing point for new users and the way to travel between worlds. The Lobby is divided into four sections of different world types: Survival, Games, Challenge, and Affiliates.
