He was very afraid because he could not swim. A bird was lying over the river and saw the ant. He dropped a leaf into the river to help the ant. The ant climbed on the leaf. A little bit later, the ant and his leaf finally made it to the bank of the river. He thanked the bird again and again.

Later, the ant saw a strange man with a net in his hands. The man was looking up at the bird. “What is that man going to do?” thought the ant, Soon the ant knew that the man wanted to catch the bird!
