Firefly and Dewdrop (1978)

The little firefly has a very important and responsible work. Every night he wakes up to light cheerful lights in the forest. The firefly really likes his work, and he gladly fulfills it. That night he went to the forest to give its inhabitants his beautiful lights. All night he admired them, and in the morning, having extinguished everything, he wandered home. The tired firefly makes an alarm clock so as not to oversleep the next night and suddenly sees in the window that one light does not want to go out. It turned out to be a dewdrop sparkling in the rays of the rising sun, which later became his new friend.
