Dozens of children got a big surprise when window washers dressed as Spider-Man descended on the outside of All Children's Hospital on Thursday.

The workers from Clearwater's HiRise Window Cleaners made several trips from the top of the building to the ground, washing windows and waving at patients.

Child life clinical coordinator Holly Ott relished the chance to bring in the super hero.

"Today at All Children's we had a really exciting opportunity to meet any child's hero, Spider-Man, climbing up the sides of the building, surprising chidren and making their day," Ott said.

The event offered kids a chance to experience something they aren't likely to encounter again. And for Ott, the best part of the appearance was the surprise.
