Using elytra in the 1×1 space in the area above the barrier grants the 'supersonic' achievement. In older versions, escape was possible with an elytra or a fishing rod, but the final version has no known way out of the lobby. The main collectables and secrets of the lobby are getting the music discs, getting all of the armor sets, the hidden old lobby, and the mob head hunts to get the the dragon's head. There are many redstone puzzles scattered around. When playing with other players, exploring the lobby can be difficult because the next game starts in one minute, although the player can create an invite-only game to gain the freedom to explore. All players are in adventure mode and are immune to any damage (just like in creative mode). It is a small 'town' in the middle of a superflat world. Upon creating or joining a server, the player spawns in the lobby.
