Tribe
From MHWiki
The Tribal Isles are home to three tribes of mice: Elub, Nerg, and Derr. The mice within each tribe are of the same power type, wear color-coordinated clothes, prefer a particular cheese, and perform specific parallel tasks or serve a specific function.
Of the three tribes, the Elub mice are worth the most points, the Derr mice provide the most gold rewards, and the Nerg are balanced.
