Zvončari are people who wear big, heavy animal masks and lots of bells, and walk around their town making lots of noise. They live in a country called Croatia, where they have been doing this for a very long time. People say that the zvončari scare away bad spirits and bring good luck for the year.
When the zvončari get dressed up, they look like big animals such as bears, wolves, or bulls. They have big furry costumes and masks with horns or big teeth. They also wear heavy belts with lots of bells that jingle when they walk. They sometimes carry sticks or whips, but don't worry, they don't hurt anyone with them.
The zvončari have a big parade every year in February or March called the "Fifth Season" or "Mardi Gras". People come from all around to watch and join in the fun. The zvončari walk through town, making lots of noise with their bells and making scary animal sounds. Some people throw candy or coins at them, and the zvončari might even give you a hug!
Overall, the zvončari are a special group of people who dress up in scary animal costumes and make lots of noise to scare away bad spirits and bring good luck. They are lots of fun to see during their big parade, but don't be scared of them, they're just people like you and me!
