JOHNSON CITY, Tenn. -

Kids are hitting the streets dressed up as their favorite characters to go trick-or-treating.

While most are going door to door in their neighborhoods, there are many children who can't.

At Niswonger Children's Hospital, doctors, nurses and other employees dressed up and handed out candy with the goal of keeping life as normal as possible for the kids who are fighting battles well beyond their years.

They transformed a room in the hospital and the kids came down from their rooms to see Elmo, Big Bird, witches and to get treats. 

11-year-old Caleb Elliot, who is still undergoing chemotherapy after being diagnosed with leukemia, is thrilled to be trick-or-treating, just like his classmates. "It's just that it was really fun because I don't get to go at my house and do it with my friends and stuff," says Caleb Elliott.

This is the third year the children's hospital has had the event.
