The goo is a liquid that can be found in Robbery Bob 2: Double Trouble. Once the liquid is released by stepping on the button, it will keep spreading, even if the player shuts it down. It can eliminate everyone so escaping faster is highly advised to avoid a game over.

The goo as seen in the trailer.


There is no way to stop the spreading of the goo, even if the player shuts it down. However, eliminating NPCs is the only advantage to the player to prevent a ruined perfect or a game over. Using the Energy Drink is optional, as it can increase Bob's running speed, good for escaping from the goo, especially if the player runs out of running power or almost receives a game over.
