Character
A caterpillar and a mantis
Summary
At first, a caterpillar was captured and confined in a bottle.
One day, a mantis came there from a window which was opened and he said to a caterpillar "You would die" with an uncomfortable gesture.
But, after doing such a thing, a mantis was captured! The person who captured him had a hobby of collecting insects and making samples, so he feared and regretted behaving unkindly to a caterpillar.
However, a butterfly came there and called his or her friends. Then, they opened a lid of a bottle and rescued him. The caterpillar which grew up to a butterfly came to rescue him!
Irony
A mantis behaved unkindly to a caterpillar and he did not try to rescue him or her.
But it was a caterpillar to rescue him when he was in trouble.
