They waved to the camera as they recovered from their ordeal.
The Thai Navy Seals have also published dramatic footage of the operation itself, showing how expert divers navigated the Wild Boar football team through the perilous journey to the surface.
The decision, a response to the global outpouring of love and support during the hard operation to rescue the boys, draws attention to the large numbers of stateless people living in Thailand, especially in its border regions.

None of the four boys who were the first group to be evacuated from the cave has a fever, and the three boys who have minor lung infections are improving, Thai officials said, adding that they are taking less medication and can eat anything they want.

Before their discovery, they survived by drinking water dripping into their cramped refuge. "None of them show a level of stress that we should be concerned about".
But Prime Minister Prayuth Chan-ocha said on Tuesday extra precautions would have be implemented both inside and outside the cave to safeguard tourists.
In a nationally televised address, Prayuth said that the government's efforts, the assistance of people in Thailand and overseas, and the outpouring of moral support made the mission a success.
"Hooyah! Mission accomplished", read another, echoing the rallying cry of the Thai navy SEALs involved in the rescue.
