Toxic Water as it appears in Portal.
Goo[1], also known as Toxic Water and Hazard Liquid, is an environmental hazard present in both Portal and Portal 2. Any contact with Goo will result in the player's death. It is usually present in order to provide a penalty for failure, and to ensure that players are precise with their movements and positioning of their Portals.
