The KoKos are funny looking characters with heads much larger than their bodies, each KoKo representing one of 16 countries. KoKo Arena is similar to volleyball, but your KoKo's head is used to hit the ball. There's only one rule: don't let the ball fall on your side of the court! You'll laugh when the power-ups do funny things, such as cause you grow in size, shrink, or turn the lights off. Beat all of the KoKos and win the dreamed KoKo Cup trophy.
