Kokonana!

From BoardGameGeek:

Every year at the Temple Festival, the best runners have a race across the Nanakoko river. To do this, they have to find stepping stones in the water, after which they must open the mystical temple with the right key. Kokonana is a lively race game in which good memory skills are useful, but not absolutely necessary. Missions are accompanied by a loud "Kokonana!" Who will remember the best way over the river and be the first to the mysterious temple?
