One day, the little crab said to the duckling and frog, I think the white clouds in the sky are beautiful. Let's draw it! The duckling said: Baiyun has only one color, and it is not beautiful at all. I think the sun in the sky is beautiful. Let's draw the sun!
The little frog said, the rainbow is beautiful. Let's draw a rainbow!
The little crab agreed with the little frog and said, the rainbow has seven colors. It's really beautiful.
The duckling also said, yes! The rainbow bends like a big arch bridge. It's beautiful. Let's draw a rainbow!
So they are going to draw a rainbow. However, although the rainbow is beautiful, it can only appear after the rain. They waited and waited anxiously. The little crab ran to watch TV, and the little duck ran to swim. Only the little frog is still squatting on the lotus leaf, waiting for the rain. Many things happen, and finally it rains. It's sunny and a rainbow hangs on the horizon. The little frog draws according to the rainbow. Soon, the rainbow was drawn. Everyone praised the little frog for his good painting.
The little frog said to the little crab, where is the rainbow you drew? The little crab blushed and said, I'm busy watching TV. Where's your painting? The frog asked the duckling again. The duckling blushed and said, I went swimming. At this time, Aunt Goat said: Look, the rainbow painted by the little frog is so beautiful because he has perseverance, but you didn't draw it because you gave up halfway!
