No one is cooler than "The Rock!" Dwayne “The Rock” Johnson heard about 3 year old Hyrum Harris' battle against acute lymphoblastic leukemia, complicated by Down syndrome, and the fact that this little boy absolutely loves the “Moana.” The Rock voices Maui in the animated movie, and that just happens to be little Hyrum's favorite character. So Johnson made a video especially for Hyrum. He said, “I heard you love a movie called ‘Moana,’ which is crazy because I love that movie, too,” The Rock tells Hyrum in the clip. “I also heard you watch ‘Moana’ almost 10 times a day because the character you love, Maui, gives you strength.” And then he sang a little bit of the song "You're Welcome." Needless to say Hyrum was thrilled.
