Run as fast as you can to reach the cheese and then hole of your choice. If you are going for first place, you can jump a little early on the way down to the cheese so you fall to the bottom floor faster.
There are two shamans on this level each with their own color hole. You will only receive credit for mice entering your hole. The shamans may engage in a shaman battle and try to kill the other shaman or block his hole before the mice reach the bottom level.
