The start-up glitch is a glitch discovered by Baltro. The glitch only appears in one level, Alice and Bob and the Third Party. This strange occurrence will only happen randomly; there is no known way of ensuring it occuring. When it does happen, the Infected Goo that normally are found moving around the pre-built Infected Goo structure are found already attached to the structure. This can be identified easily as when the level begins and the camera looks around, you will hear the distinctive noise goo balls make when they connect. This will sometimes only affect a few goo balls, other times it will affect them all, and the player will be unable to complete the level because they cannot access the pipe.
