Disney Frozen Pop-Up Olaf Game is quick and easy to set up. Simply twist Olaf into his barrel and take turns to slide in the crystal sticks. If nothing happens, you're safe, but if your crystal stick makes Olaf pop up out of this barrel, you are out! Keep playing in rounds: the last player left is the winner! Remember, every time you put Olaf back in the barrel, it will be a different hole that will make him pop. You never know if you'll be next to go!
