Fang suggested to the two dragons that they do pull-ups to compete. They nodded and Kredech thought he would be the winner because he was skinny and that Yang would not make a single pull up with his weight.

Later it was Kredech who could not make a single pull up, while the fat dragon was already at 20: slowly but steady and with a loud wheeze. Fang taunted Kredech because he was so sure he would win and also for payback for his smugness.
