A little boy was playing outdoors and found a fascinating caterpillar. He carefully picked it up and took it home to show his mother. He asked his mother if he could keep it, and she said he could if he would take good care of it.
The little boy got a large jar from his mother and put plants to eat, and a stick to climb on, in the jar. Every day he watched the caterpillar and brought it new plants to eat.
