When a player reaches the highest score on the scoreboard, they will become a Shaman in the next map involving one. The general objective of the Shaman is to help the other mice to reach the cheese and bring it back to the hole. Doing so will award the Shaman with “saves” for each mouse who completes the map, which are recorded onto the player’s profile. The Shaman can do so by summoning objects such as boards, boxes, anvils, spirit, and balloons to create buildings or contraptions such as bridges to cross gaps or various other obstacles. A shaman can ‘anchor’ or connect boards and boxes to other world objects or summoned objects with various-colored nails. Red nails keep an object firmly grounded and will not move, but it can rotate on the anchor. Yellow nails connect to most other objects, particularly red-nailed ones, and keep an object’s placement, but can move. Green nails connect two objects but are loose and can rotate an object.
Upon reaching 1,000 total saves as a Shaman, a player can choose to become a ‘hard mode’ Shaman. In hard mode, a Shaman cannot use red nails which anchor an object solidly, nor can they use the Spirit tool, which can push mice and objects with a flash of light. In lieu of this, hard mode Shamans can create a pre-made ‘totem’, which is constructed on an in-game editor map. Totems can be constructed with up to 20 objects, but only one red nail may be used as an anchor. A completed totem construction can be summoned instantly as a hard mode Shaman and is immediately functional, but may only be summoned once per map.
