Transformation is an ability which allows mice to turn into shaman objects.

Mice are supposed to help each other out with this ability, but it can also be used to troll and kill other mice.


It is given to all mice on maps 200 to 210. These maps play when there is a medium amount of players (5 to 16) in the room.

However, it can also be obtained on any other map if the shaman has the Transformice Skill icon - Transformice.png skill, which allows the shaman to give this ability to up to 5 mice.

Mouse transformation icons appear in the shaman items box on the bottom right of the screen. Once a mouse is transformed into an object it is not able to move, and a single mouse icon appears in the item box instead. Clicking the mouse icon reverts a player to their mouse form.

These are the objects a mouse can turn into:

Current maps[]


The ability was introduced on 30 April 2011 with V0.154.

According to game co-creator and administrator Melibellule, the concept of mice "transforming" into objects (thus the name Transformice) was to be the system of moving about on the map, but proved to be difficult or impossible with only a few players in a room. As more began to play the game, the concept was re-introduced by adding maps 200 to 210.

Event items[]

During events that have collectible items outside event maps, such as St. Patrick's Day, transformed mice will still hold the event item if they held it before transforming.


  • The face of a mouse may disappear when it is transformed.

  • A transformed mouse's body will always be brown, no matter what fur they have.
  • There are plank skins that looks like transformation objects: Small plank skin #36 (short plank) and Large plank skin #39 (long plank).
