Interesting combination! Chhota Bheem is a popular Indian animated character, and Petra is a famous archaeological site in Jordan.
The movie is inspired by the real-world archaeological site in (though the movie mentions Egypt, the real Petra is a famous Nabataean city in Jordan).
They see ancient carvings: camels, merchants, and a symbol of the sun. Bheem notices water channels carved into the walls. “This city knew how to save water,” he says.
