Mario and the gang are invited to Party Island to do as the name implies. To insure nothing can go wrong, the Koopa Troop is also invited! The Kongs also get the invitation. Seeing as how Donkey Kong and Diddy Kong are invited, King K. Rool sees this as an opportunity to eliminate DK once and for all! Bowser hears word of the invasion and tells everyone. But following the saying: "the show must go on!", Bowser also decides to turn it into a competition, thus bringing about Mario Party 10.
