A parable. The six little pigs are perfectly happy together until one notices that Paprika's tail is straight instead of curly. Paprika wants to hide. Everyone laughs at him, and he goes to his mother who tries to help. She uses a curler, but the tail straightens anyway, a knot hurts too much, and a knitted curly tail looks silly. When a purple frog comes along and finds something different about each of the six little pigs, they learn to accept differences, and the frog has to accept his too: 'We're six perfectly different pigs and one perfectly purple frog'.
