SPOKANE, Wash. -

When you find Storm Troopers, Ghostbusters and puppies in the same room, it has to be for one epic party, and that's exactly what happened at Sacred Heart Monday.

While costumes and candy are a staple at every Halloween party, it meant much more for the children at Sacred Heart.

"It's just a fun day to really hear a lot of giggle in times when it's hard for families," said Kirsten Carlile, director of family support services at Sacred Heart.

While many of the children spend their days fighting for their life, Monday, they got to forget about their illness and focus on fun.

And the event wouldn't be possible without the help of volunteers. They bring their pets and some even dress up as beloved characters from a galaxy far, far away.

"I came in off the elevator and I looked over and saw Darth Vader right there and I was just like 'oh,man! Alright, I'm on the dark side,'" said Melissa, whose child is being treated at Sacred Heart. Her son, Dylan, was diagnosed with Leukemia on May 17.

Melissa, who didn't want to give her last name, says when she arrived at the hospital Monday morning, she had no idea the party was going on. She says she couldn't be more thankful the hospital is giving her son a reason to smile this Halloween.

"I love Halloween, it's one of my favorite holidays. So, I just love that they're putting a lot of effort into it and making it fun," she said.

And for the volunteers, seeing the kids smile makes it all worth it.

"A day like today, where the kids are able to come in and enjoy doing their little festivities with their cookie making and visit all the dogs... they're out of bed. That's just a huge thing for all of us to see," said Scooter Mahoney, director of pet visitation at Sacred Heart.

Sacred Heart says these parties aren't just for Halloween either. Parties will be held for every major holiday this holiday season.
