Santa needs wool for his new coat and the coats of his elves. If you give Santa Claus wool on your turn, you may move him to a hex on the island of Catan. Once he arrives on the hex, he gives the settlers Christmas gifts and may even chase away the robber and/or to protect a hex!
This expansion increases the strategic value of wool, which in the basic game is considered the least attractive commodity.

This variant scenario is suitable as an add-on for up to 6 players and all expansions that include the robber.
