The last thing Dillon Ford should have done was to throw a tennis ball at the squirrel. He didn't mean to hit it. And he certainly didn't mean for it to fall out of the tree. But now the squirrels are after him. They have the house surrounded. They're on the roof, at every window, and coming down the chimney and through the mail slot. Dillon is a boy under siege and one thing is for sure...the squirrels are pretty nutty!
