Roro Anteng gave birth to a child, then another, and another. In the end Roro Anteng and Joko Seger got 25 children. Soon it was time for them to sacrifice the youngest child, Kesuma, but the parents just could not do it. They tried to hide the child, but an eruption happened and Kesuma fell into the crater. There was silence before they heard a voice: "I have to be sacrificed so that you will all stay alive. From now on, you should arrange an annual offering ceremony on the 14th of Kesodo (the twelfth month of Tenggerese calender."It was Kesuma's voice.
Kesuma's brothers and sisters held the offering ceremony every year. Instead of a human being, these people collected fruit, vegetables, rice and meat to be offered to the gods. And this has been done generation after generation until today.
