Water Lock is a level in the video game World of Goo. It is the seventh level of Chapter 3. In this level, the player is pitted with a Spike Goo and numerous Dark Black Goos, with a rotating massive wishbone-like structure in the middle. Some may be confused and think that the player has to work around the wishbone, but it is actually more simple than that. The player must latch the Spike Goo onto the ball of the wishbone, wait until at bottom, then detach the Spike Goo. This launches the structure towards the pipe. However, the momentum also flicks huge numbers off, so the player must repeat the aforementioned steps.
