2. Tribe
Ever wondered how you get friends and play with mice? Well thats all dealt with! Tribes are here for you! To get a tribe of your own, gather 500 cheese it must say 500 cheese in the shop to work. Then the second thing to do is get a greeting message! Once that is dealt with, get some tribe members! be sure to choose the right rank for them. If you would like, Edit your ranks with new names! I edit mine with details that go with my tribe name.

3. Shaman
Have you heard of a shaman? well if you have, shamans are in the game! They are the ones who help the mice get the cheese, and return to the hole! Sometimes, there are 2 shamans! They can do teamwork, or the pro shaman kills the other one. Have you seen the name that says: Your the shaman! Help your disiples get the cheese! See that tab on the right? Press Different letters to tie stuff together! If you would like to tie a balloon to a mouse, press B and click the middle of the mouse. to summon a ghost object, press SPACEBAR. Be sure to get lots of saves!

4. Skills

Have you seen these numbers by a shamans username? That shows how many skill points they have used! what are skill points? They are points that you use to make your shaman have more powers! each skill point you get adds more to your total. To get your points that you have previously used, press Restribute. Conform and pay 34 cheese. The cheese total depends on how much skill points you used. press bottom skill boxes to unlock more skill boxes! Use your skill points wisely!

5. Clothes

Have you been seeing mice with clothes on? to get them click "Menu" At the right of your screen. Then click "Shop"
