Life can be boring for a caterpillar. Aelfryn wanted something more to do than just eat leaves. His friend Owl suggested that he looked in through the window of the house next to his tree - a school of dance. Tap-dancing, disco dancing and ballet are taught there and with the help of his friends Aelfryn has a go - he would love to be able to dance. But caterpillars were not made for dancing. After all his effort and disppointment Aelfryn is tired, so tired and begins to spin himself a nice silky bed so that he is completely covered up. His friends can't understand why he won't speak to them until the day he does wake up and finds that he now has fewer legs, beautiful jewel coloured wings and that, best of all, as a beautiful butterfly he can dance.
