When you uninstall cs:source

= when you uninstall cs:source = when you uninstall cs:source is a tool found in Sandulator.The tool appears to be a 2x2x2 stud cube with a purple and black checkerboard texture, a reference to the Missing texture used in Valve games.

The tool's name seems to be a reference to the sandbox game GMod, where a lot of user generated content uses Counter Strike: Source Textures and 3D models. Not having CS:Source installed will cause textures to go missing, hence the tool's appearance.

The tool's description reads; "hahhahahhhh"

Obtaining
The cube can be obtained by going off the map at the same corner as the Dev Island, then landing on a yellow neon brick.

The cube is most easily obtained by going up to the Hexagon Caves island and typing "666" into the phone located on top, then pressing call. This will spawn in a large sphere with the scary face on all sides. Touching the sphere will give the player a speed bost, akin to an Enchanted Beet. The player should then immediately jump off to the left of the Hexagon Caves island and start running toward the Dev Island. Then they should aim to stop at the edge right in front of the Dev Island, and slighty to the right. When the speed boost runs out the player can drop down onto a yellow neon brick. Doing so will give the player the item as well as teleport them to the Sand Mart. At this point the player will be taking continuous damage by a Grue, so dropping the item before the player dies is advised.

Usage
When the player uses the item by left-clicking, a Fart with extra reverb sound effect will play. After about 3 seconds the item dissapears and the player will be given a toxin level of 11.
