As Halloween approaches, athletes have been getting into the festive spirit early this week. This time, players from the Boston Bruins donned costumes for their annual trip to the Boston Children's Hospital on Monday.

The B's dressed up as characters from the Disney hit-movie Frozen. A picture shared by the team's Twitter account shows Kevan Miller, Dougie Hamilton, Matt Fraser, Seth Griffith, Matt Bartkowski, and Torey Krug in their costumes:

Hamilton and Fraser must have drawn the short straws and ended up having to dress up as the lead characters "Elsa" and "Anna" though they pull off the looks fairly well. Miller also impresses as Anna's love interest "Kristoff," complete with the blond wig and fur vest. Bartkowski passes for Kristoff's reindeer, "Sven," and Krug looks comfortable in a puffy suit as he portrays the snowman, "Olaf." Finally, Griffith rounds out the team as the movie's main villain, "Hans."

"I think it's fun, whatever can make them smile," Hamilton said, according to NESN. "It's all about fun for them, so no shame at all."

The players went through the hospital surprising patients in their rooms and handing out candy. They even broke out in their rendition of the hit theme song, "Let It Go," as they walked through the hallways.

"Just here to put smiles on their faces," Krug said. "They love it. It's a very popular movie, my niece loved the movie, always sings 'Let It Go,' so it's a very popular thing, and makes them happy, so that's the most important thing."
