Today is Coke and Pepsi McDonald’s thirteenth birthday. Someone’s out to make sure they never make it to thirteen and a half.Racing across America, the twins will nearly beboiled alivein a huge basket of french fries, frozen to deathby soft-serve ice cream, stampededin a wild stadium riot, kidnappedfrom a high-speedroller coaster, andworst of alltheir parents thinkthey’re totally joking!Will they survive? Will they defeat Archie Clone? Will they be dropped out of a helicopter onto the tip of the Washington Monument? Will they ever say “genius”?
