The spirit is a shaman power that creates a small explosion anywhere on the map, repelling all mice and physical items around it. The spirit is most commonly used to propel mice short distances, over gaps and small ledges. This is practically required on Map10. Unlike most shaman powers, it can be used from any distance. Spirit can't be used by shamans that are in hard mode.
The spirit has the ability to "reset" anchors to the origin point (0,0), which is located at the top left of the stat bar. It is performed by using a spirit precisely in the center of a red anchor. Any red anchor put on the map after a anchor has been "reset" will disappear to the origin. This is useful in Map62 for one well placed shot can make the anvil god disappear. Sometimes, sync issues cause it to seem like the effected items are falling down then teleporting back to the origin point constantly. However, this glitch has been fixed.
Spirit glitching is the act of a user teleporting to the top left corner of the screen. It can only be seen fully if you have fullscreen enabled.
How you do this is, get the spirit, press C, and center it in your mouse. It should almost be at the end of the arms. Being there makes you unable to walk. You are stuck up there. It is also known to be done by attaching a balloon to a mouse, b planking it and using the spirit glitch. You can escape in this, but it usually results in death. However, this glitch has been fixed.
Some users use third party programs to automatically hotkey the spirit and click in a distinct pattern so as to form an image. Smiley faces and hearts have been seen. It can be also used for trolling, by "drawing" inappropriate images.
The super spirit, more commonly known as the red spirit, pink spirit or ghost spirit was the stronger version of the standard white spirit. It was 250% more powerful and had a 125% greater range than its unghosted form. The super spirit was silently added into the game on August 5, 2010 in version .50 without being mentioned in any patch notes. It was accessed by pressing space while having spirit selected, turning it red, where it could be used like a regular spirit and without following the usual rules of ghosting.
On August 8, 2010, the ghost spirit was removed from the game. Later that day, Transformice commented on the official Twitter that it had been put into the game as a test. It is unknown whether it will be reintroduced later like warps. On November 21, 2010, super spirit is returned. But it's not a super spirit, it's a pink spirit looking like a super spirit with the same attributes as a regular spirit. It can be acquired the same as a super spirit by ghosting a normal spirit.
