In Animal Crossing: City Folk and Animal Crossing: New Leaf, the player can go to Shampoodle and Harriet will give the player a Mii Mask after the player requests a makeover. The Mii Mask replaces the player's head with one from any Mii saved on your Wii or 3DS. Accessories and hats are removed when the Mii Mask is worn. If you want to change your Mii Mask, you must ask for a makeover from Harriet and pay 3,000 Bells, if you change the mask on the Mii Channel/Maker it will be changed in your game. Mii Masks can be put on by using the Design window, though there must be pocket space for any accessory or hat the player is wearing. It can be removed at any time via the Designs window or putting on an accessory or hat, which sends the Mii Mask back to its spot in the Designs window. Bee stings will not show while wearing a Mii Mask, though villagers react as though they can see them. Miis have different expressions when the player uses emotions.
- Even though it is just a mask, the Mii Mask will display various emotions.
- In City Folk, if the player puts on a Mii Mask with a different skin tone, the player's arms and legs will become that skin tone too. However, in New Leaf, the skin retains its original shade.
- To change the Mii Mask to another design through Harriet costs 3,000 bells, and it is free to edit the Mii on which the mask is based, it is wise to make a Mii called "Mii Mask" and simply alter that when a change of style is desired.
- If you look closely, just a little bit below the head, you'll see a part of your body that is a different color than that of the mask (depending on the Mii's skin tone and your tan level), the part just under your head will be your character's actual tan level.
