Kori shared a clip of Depp donning his popular pirate outfit in his new YouTube channel called "Kraken the Box," which showed the content of Depp's special message to him.
"I wish you the best of luck. I am your number one fan, Captain Kori. All the respect and love, mate," said Depp.
The 59-year-old actor also promised to encourage friends to follow Kori's YouTube channel. Dwayne Johnson heard that loud and clear and followed the young boy.
Kori now has 170,000 awesome subscribers on YouTube, and fans are showering encomiums on Depp for being so thoughtful. One fan commented,
''Love or hate Johnny Depp, but you can't deny his true love for caring and sending wonderful messages to sick children. This man has a heart of gold!''
