Legong is like a special dance from a place called Bali. It's kind of like a story that people tell through dancing, like when you pretend to be animals or princesses or superheroes when you play with your friends.
The dancers wear beautiful costumes and they move their arms and legs in very special ways that make the story come to life. Sometimes they use really pretty fans to make their movements even more special.
Legong is a really important part of Balinese culture and it's been around for a really long time. When people watch the dancers perform, they feel happy and excited and they can imagine themselves in the story that the dancers are telling.
