a caterpillar wake up to find out that he was caught in a bin (jar?). he tried to escape somehow but he couldn't. then a mantis came. he found a caterpillar in a bin being caught. however he easily gave up to save the caterpillar even though he could fly. when the mantis was about to go out, he got caught, too. when he woke up, he was inside a bin, too. he tried to escape like the caterpillar did but he also couldn't. then a butterfly came in. the butterfly gathered some fireflies with him and helped the mantis. the butterfly was the caterpillar.
the problem was that the mantis also got caught.
the caterpillar had such a warm heart. the caterpillar helped the mantis who did not helped the caterpillar.
what this movie wanted to tell us is that we should keep having the kindness. when someone needs help, we should help him/her.
