His front wheel had made it when it came out of the puddle. Pete noticed it and he was pleased. “I meant to do that,” he laughed. (But he hadn’t really.) So he rode right through the next puddle, and his black line shone behind him. But now. when he looked around, instead of one black line, there were three, because this puddle was a very big one, and all three of the wheels had gone right into it.
