A Cookies and milk on a table building.
This building will call Santa Claus to your island every 7 days and will do the following:
1) Transform your island into a Winter Wonderland for a day.
2) Cause a Christmas tree to grow somewhere on your island and when clicked upon will give you a present of a token, a gem, a guide, or a Tree Coin.
3) There is a 10% chance for another tree to grow on your island somewhere each day as long as you have the building on your island.
4) Finally, Santa will hide 10 presents somewhere on your island which can contain resources, weapons, a gem, a GC, coins, a book, resource refill, a small present, or a Tree Coin.
5) The small present can be traded for a token or a Tree Coin when you collect 10 of them in the PH.
6) 100 tree Coins can get you a special general, explorer, geologist, or a token building.
