A fun Frozen inspired party game to play is "Pin the Carrot nose on Olaf." Played like "Pin the Tail on the Donkey," the game can be bought or made with a poster of Olaf and carrot noses for kids to pin on while blindfolded.
Kids can also play the snowman game with a couple rolls of toilet paper. Divide the children into two or more teams and have them pick a child to wrap up; the first team to make a complete snowman gets a prize. Then let the kids have a toilet paper "snowball" fight with the unwrapped toilet paper after the game is done.
Another great idea is to play the music soundtrack and have the party goers play freeze dance. Stop the music at various intervals and tell the kids to freeze when the music is off.
