Drool is a level in the video game World of Goo. It is the first level of Chapter 2. In this level, the player is introduced to Water Goo and must use it to build structures hanging downward in order to reach both the exit pipe and some sleeping Green Goo.
Quite simply, build down with the Water Goo to get to the Green Goo in the water, making each leg as long as possible (you have to get down there using only 6 Balls). Once they begin waking up, start carefully building to the pipe (do your best not to lose any to the spikes). Once done, get the rest of the Goos in and try to make your Green Goo structure as dangly as possible without getting it destroyed on the spikes. After, use the same "last Goo Ball" method from Ivy Towers and Tumbler.
