I'm unsure why it's snowing, I've tried to make it stop, even it slow down. However, sadly my abilities are no avail.
What I have done is make a Winter Festival in Arendelle!
There's sledding, ice skating, snowman field, snow forts for snowballs battles. A place to sit and just enjoy the view while sipping on your choice of drink.
Come to Arendelle if you'd like to have some fun in this beautiful weather.
