The MuiMui (ムイムイ) are the LocoRoco 's friends. They are one of the main "items" that can be found and collected during the levels in the LocoRoco series. They are usually hidden in the levels, off the beaten path and sometimes are difficult to find. In LocoRoco, the MuiMui you find contribute to music in the Loco House, whereas in LocoRoco 2 , MuiMui have their own house in BungaBongo. MuiMui found immediately go to the MuiMui House. In LocoRoco Midnight Carnival, each MuiMui found adds 100000 to the total score.
