Leap Hole is a level in the video game World of Goo. It is the sixth level of Chapter 2. In this unique level, the player must first build a structure of Green Goo up to a pipe, and then strategically dismantle the structure in a way that takes advantage of the pipe's suction, a technique known as pipe hanging. Upon clearing this level, the player gains the whistle, which allows them to attract Goos toward their cursor at will.
