Tale originated from Philippine.
Juan is a lazy boy. One day, his mother asked him to buy crabs for dinner. On the way to go home, with a basket of crabs, Juan saw his friends. He wanted to play with his friend, thus he released the crabs and told them to go home first. Later at night, he went home because he was hungry, only to find that there was no dinner and he was punished by his mother.
