The stars joined together to visit the patients at the Seattle hospital and the Odessa Brown Children’s Clinic on Tuesday.
The trio posed for photos with the patients and greeted the children receiving treatment at the hospital.
“Hanging out with our friend @prattprattpratt,” the hospital wrote on Twitter. “Thanks for being #StrongAgainstCancer!”
The tweet included a photo of the Jurassic World star with one of the patients. The actor held tight to a toy figurine of Groot from his film Guardians of the Galaxy.
“Had the most amazing day at @seattlechildrens hospital,” wrote Pratt on his Instagram. “Got to meet a ton of great kids and parents. Also got to spend some time with one of my personal role models @dangerusswilson and his lovely lady Ciara. I am truly living the dream.”
Pratt asked his followers to “say a prayer for all those kids who don’t get to be at home for Xmas,” and shared a Bible verse.
The couple, in partnership with Amazon, brought “two larger-than-life gift boxes filled with toys, Amazon devices and gift cards” for the patients.
“Thanks @Amazon for the @AmazonKindle for All 300 patients in @SeattleChildrens today from @Ciara & I,” Wilson wrote on Instagram.
Some of the presents included different versions of Kindle readers, which was especially exciting for 16-year-old Joseph Thomas.
“It was really nice and surreal to see him today,” Thomas, who is recovering from a spinal cord injury, told the Seattle Children’s blog. “It’s the thought that means the most. He really cares.”
Pratt also regularly spends time visiting sick children at care facilities across the country.
