There are a number of fun things to do while playing with the reindeer outside the barn. Tap a reindeer to call it over to you.
From here, you can feed the reindeer from the hay trough, give them water from the pitcher, or tap on the stables in the back for a well-deserved nap! With all of that eating and drinking, nature is bound to take its course. Use the broom to clean up the droppings left behind and collect them for use as garden manure.
You can also say hello to Anna and Kristoff by tapping on them.
