On his first day at a new school, eleven-year-old Billy goes up against the school bully in a challenge that ends up with a total gross-out date...to eat 10 worms in one day. As the pressure mounts, Billy must summon all his strength to meet the dare, all the while keeping his weak stomach from betraying him and his big mouth from getting him in even more trouble.

Against his mother's wishes, Ben will secretly enter the local soapdox derby to best school bullies. With a rag-tag group of friends, the 12-year-old will encounter a crazy cast of characters while building and racing his own car.
