"Guardians of the Galaxy" star and former Lake Stevens resident Chris Pratt is asking you to donate to help Seattle Children's -- and you might get to meet him on the set in the process.

Pratt, who is in Hawaii filming "Jurassic World 2," is teaming up with Makenna Schwab, 14, to raise money for the hospital. Schwab has Larsen Syndrome, a rare connective tissue disorder. The National Institutes of Health says "affected individuals are usually born with inward- and upward-turning feet (clubfeet) and dislocations of the hips, knees, and elbows." Schwab has undergone 15 surgeries at Seattle Children's.

Pratt wants you to help other kids like Schwab. He posted this on Instagram.

“Wanna come visit me on the set of the #jurassicworld sequel? In HAWAII!?!? The answer is, “YES!” Of course you do!
