Play 'Once Upon a Time's' 'Frozen'-themed drinking game

It’s about to get very chilly in Storybrooke.

When Once Upon a Time returns for its fourth season, Frozen’s Elsa will make her way into town after spilling out of an urn that was locked in Rumpelstiltskin’s vault in the season finale. Suffice it to say, she will not take too kindly to strangers and will quickly lose control of her powers, sending Storybrooke into the next ice age. With that being said, EW created a Frozen-themed drinking game to make watching the show’s return even more fun.

Disclaimer: Yes, we know Frozen is for youngsters. They can chug apple juice, while those old enough should responsibly imbibe in a frosty beverage.
