In keeping with their annual Halloween tradition, the Boston Bruins visited kids at the Boston Children’s Hospital on Monday afternoon.

In recent years, the costumes have lacked a coordinated feel—ZdenoChara’spink bunny suit or Dougie Hamilton dressed as a gigantic baby were the standouts among the seemingly random outfits. This year, however, the B’s stepped up their game, with Hamilton, Matt Fraser, Kevan Miller, Matt Bartkowski, Torey Krug and Seth Griffith taking to the halls of the hospital dressed as characters from Disney's hit movie Frozen.

Third-year Bruin Hamilton impressed in a sequined blue dress and blond wig, twirling about the hospital as the heroine Elsa who, like the defenseman, is no stranger to working with ice.

Fraser sported a red pigtailed wig and what appears to be a child-sized costume as Elsa’s younger sister Anna. The not-so-modest outfit revealed a pair of gym shorts, the likes of which would not be seen in Arendelle. Even with a separated shoulder, Miller wears his Kristoff costume well. Complete with a red sash, fur vest and enviable blond locks, the California native looks fit to take on the role of Anna’s love interest. A bearded Bartkowski portrays the loner’s reindeer and best friend, Sven. Krug brings the role of talkative snowman Olaf to life, looking comfy in a cushy suit, while Griffith rounds out the group as evil-yet-dreamy Hans.

The players even occasionally launched into renditions of "Let It Go," which made it difficult to tell who had the most fun during the visit: the Bruins or the children.
