The whole neighborhood is preparing for a street festival to raise money for a new pool. Benjamin Bean can hardly wait. It's going to be a fantastic fiesta with dancing from Columbia, food from Equador, and music from Mexico. Even getting ready is a lot of fun--until everyone starts fighting. With Anna and Sarah not speaking, Senora Sanchez arguing with her cousin, and Benjamin's younger brother Adam driving him absolutely crazy, the fiesta is turning into a fiasco. Somebody had better do something to bring everyone together fast.
