Impale Sticky is a level in the video game World of Goo. It is the fourth level of Chapter 1. In this level, players must use Black Goo to build a structure around a ledge to reach the sleeping Goo and the pipe, while avoiding two blades that will pop any Goo they touch. This level also introduces time bugs, as referenced by the in-game level description: "If you get in trouble, just go back in time!" In addition, this level has a strong airflow which drags all the objects to the right side of the screen. Airflow and water are their strongest at the left side of the screen.
