Two Thai artists created a cartoon full of hidden symbols to depict the successful efforts to rescue the Thai soccer team trapped in a cave — and it went viral. 

The cartoon, created by Sisidea, has been shared thousands of times on Facebook. The Royal Thai Navy shared it as well.

The cartoon shows 13 wild boars, representing the stranded members of the Wild Boars soccer team, swimming out of a narrow underwater cave alongside dozens of other animals, which represent the countries involved in the rescue efforts. It even features Elon Musk, the SpaceX and Tesla CEO, as Iron Man.

Every animal in the cartoon has a special meaning:

Wild boars (12 small ones and one larger one): the stranded boys and their soccer coach. 

White elephant: Narongsak Osottanakorn, the leader of the command center in charge of the rescue mission. 

White horse: all the heroes who were involved in the rescue mission. 

White seals: the Thai navy SEALs who have been leading rescue efforts. 

Frogs: the cave divers who have been helping with the mission. 

Blue lion: rescuers from Britain and Belgium. 

Kangaroo: rescuers from Australia. 

Panda: rescuers from China. 

Crane: rescuers from Japan. 

Moose: rescuers from Sweden. 

Tiger: rescuers from Myanmar. 

Brown elephant: rescuers from Laos. 

Eagle: rescuers from the US. 

Iron Man mask: Elon Musk, who has been tweeting his support for the rescue effort. 

Swallows: climbers from Thailand. 

Dog: a K9 unit at the scene. 

Dragon: the team drilling into the cave and pumping water out. 

Birds (facing all the animals at the end of the cave): journalists covering the rescue mission. 

Black crow (among the birds): people criticizing the mission. 

Aruni Aunhawarakorn and Jantima Manasviyoungkul, the sisters behind Sisidea, said they thought to create the graphic when they heard the soccer team was missing, but they didn't put pen to paper until reports of the first successful rescue were released on Sunday. 

The sisters, who live in Bangkok, told Business Insider, "This picture is to show appreciation from the Thai people to the collaborative efforts of many people from around the world. These 13 footballers are represented as the little wild boars. Tons of kindness has been flowing from many countries and specialist teams, so I am representing all of them in the cartoon."
