There are several versions of Keong Emas known in Indonesia. The most common one is the legend describing the romance, separation and reunion of Raden Panji Asmoro Bangun and his wife Dewi Sekartaji. It all starts when the King of Antah Berantah kingdom desired to take Dewi Sekartaji as his wife, and to do so he kidnapped her. The god Batara Narada saved Dewi Sekartaji by changing her into a golden snail. The god told Keong Emas to drift along the river in order to find her husband, Raden Panji Asmoro Bangun.

One day a poor old widow, Mbok Rondo Dadapan, who always fished along the river, found the golden snail and took it home as a pet. There, she put the snail in a jar and took good care of it. All of a sudden, unexpected good things began to take place in Mbok Rondo's life.

Coming back from her daily fishing, she would find delicious dishes on the table and the house cleaned. She wondered who had been so nice to take care of her house, to do the cooking and house chores. This strange event went on for several days, she could not resist finding out who was the mysterious and kind person was. So, one day, instead of fishing, she peeped through a hole in the wall of her house.

After waiting and hiding, she saw an amazing scene: a beautiful princess coming out of the jar and starting to clean the house and prepare the meal.

The next day, the same thing happened. Without wasting any time, Mbok Rondo rushed into the house and smashed the jar, together with the snail shell in it, with stone mortar. The now-homeless Dewi Sekartaji could not turn back into a snail shell, and the magic spell was broken. She was then adopted by Mbok Rondo as her daughter.

Meanwhile, Raden Panji Asmoro Bangun was searching for his wife. He wandered from one village to another, finally reaching Dadapan village where he found his beloved wife. Filled with happiness and love, they went back to their kingdom, taking good old Mbok Rondo.

There are several versions of the story concerning the cause of the princess being magically turned into a golden snail. One version says that Dewi Sekartaji was transformed by Batara Narada to help her escape from captivity; another version explains that a magic curse was cast upon her by her jealous sister Dewi Galuh Ajeng, a witch who also wished to marry prince Panji.^[1] In another version, the princess accidentally stepped on a snail and broke its shell; the snail was an evil witch in disguise, who then put a curse upon the princess. The other parts of the story, where the princess was saved by an old widow and she periodically transformed back to her human form to repay the kindness of the old widow and finally reunited with her husband, remain the same.

Keong Emas is a popular Indonesian fairytale, told for generations, and is often featured in many children's storybooks. The moral taught to children is to be kind and grateful, willing to repay the kindness they have received from others. The tale of Keong Emas inspired the architectural design of Keong Emas IMAX Theatre in Taman Mini Indonesia Indah, Jakarta.
