It's probably a glitch. I dunno if you can bypass it with...something...IDK...maybe the staff. It's beyond the bridge, but it's probably also in untitled52. There's stuff beyond the bridge, but mainly it's just a laggy-as-heck room with a mass of Froot Loops falling from a pipe. Which will probably be changed later after some versions. After Version 0.29 after a bunch of GD development.
