There is nothing the mice can do on their own to beat the map.
They must wait until one of the shamans start helping out.


This is a Dual Shaman shaman map with two different-coloured holes and shamans.
As a shaman, you will only receive saves for mice who enters the hole of your colour.
The shamans may fight each other to get the saves for themselves, or race to be the first one to build and let the mice choose which hole they will enter.
As a shaman, build a ramp, elevator, or an airship, or you can place springs to let the mice jump up to the platform with the two holes - if you have the Spring skill, that is.
