Form A Line
If you watched Tom and Jerry in your childhood, you would definitely remember that cute yellow duckling. It had a mother and a couple of duckling siblings and they went everywhere together. Well, this picture is exactly like that, but with one difference.
The difference is that, instead of a duck family, it is the mother and baby pigs that are walking together in a line. It looks so cute seeing all the babies coming after their mother in a perfect queue. Maybe she is teaching them how to walk.
