Cfmbot is a bot located in Room *801 whose main purpose is to help with the running of the Cheeseformice leader-boards and forums. It was created by Sourdough who is also the main developer behind CheeseForMice. The bot was originally created to allow players to link their CheeseForMice account with their Transformice account without giving away their password. However, it does have some other small features some of which can be seen below.
Contrary to popular belief, the "cfm" of Cfmbot does not stand for CheeseForMice. This is a common misconception, but it is wrong. It is up to the user to determine the true meaning of "cfm" for themselves.[Citation needed]
Its current Title is Adorable Mouse due to having only gathered one cheese but does have 4 titles in total. Its the Spiritual Chief of the CheeseForMice tribe and it automatically promotes members of the tribe based on their contribution on the forum.
There are three public commands. However there are some other 'easter-egg-like' commands which are up to the players to find them out. To issue the command, simply whisper it to the bot.
- Stalk <username> - If the given username is connected to Transformice, it replies with the server(s) they are currently playing on.
- Modlist - Replies with a list of public moderators that are currently online on the current server.
- Mapcrew - Replies with a list of users who are responsible for maps' statuses, including special maps such as for bootcamp, baffbot, survivor, etc.
- Helperlist - Replies with a list of online helpers. Note: these are not mods, but they are there to answer general game questions.
- Joindate - Saves your registration date to your CheeseForMice profile.
