But Nell had watched Kevin use this tactic on other kids, and she knew 
that it only worked because usually the kids were too scared to move. Dojo had 
explained to Belle that the best way to fight Dinosaur was simply to get out of 
his way and let his own strength defeat him, so that's what Nell did with 
Kevin: stepped aside at the last minute, made one foot into a hook, and tripped 
him. Kevin smashed tremendously into a swingset, gathered himself up, and 
charged a second time. Nell dodged him and tripped him again.
