Ooops, said Blurtso, as he let his hoof slip across the line he had drawn in the sand. 

                
Ooops, he said, as another hoof crossed, followed by his haunches, his rump, and his stumpy little tail. Ooops, he said, turning and sweeping the line with his boxing-glove nose, then stamping and stomping and tromping until there was no mark left at all. Very good, thought Blurtso as he surveyed his work and considered his new-found freedom. Freedom? he thought, looking in the direction where the others had gone. Wait for me! he cried, scampering off to join them.
