"How do you do?" Depp, 52, said as he greeted children and hospital staff on Thursday.
In this video from Juiced TV, a TV show "made by the kids in hospital, for the kids in hospital," Depp can be seen touring the quarters, shaking hands, giving hugs and being as cool as you'd assume him to be.
Clearly, the kids were in awe as the actor raised their spirits and gave them something to smile about.
One child, Ula, wasn't sure what to expect when the hospital teased her with the news of a surprise. "It could be anything," she said, nervously anticipating the big unveiling.
When the surprise was revealed to be Depp -- er, Sparrow! -- she was in tears.
Taking a break from shooting the fifth Pirates of the Caribbean film, Dead Men Tell No Tales, Depp hung out with the kids for over three hours, giving out plenty of gold coins and taking selfie shots.
Not that they'd need those pics -- this will most certainly be a memory they'll never forget.
