A little caterpillar was born on Sunday morning, but its stomach was so hungry! So he decided to find something to eat. He ate an apple on Monday, two pears on Tuesday and three plums on Wednesday. He kept eating all week and finally had a stomachache on Saturday. After eating a piece of green leaves on Sunday, the fat and big caterpillar began to sleep in the pupa built by itself. After more than two weeks of dormancy, it finally transformed into a beautiful butterfly.
