Mysterious box

The Mysterious Box is a beta item for. It appears as a black, glitchy box in your pockets, but when dropped and when you walk into another acre and back, there will be a strange, floating, yellow box. It moves from left to right and can push the player away. After a while, it glows a very bright yellow, then dims back down. It is unknown what it was/is used for. Some have guessed it has to do with the lighthouse, since it flashes a bright yellow color and dims out.
