Princess Toadstool is fed up with Koopa's antics and challenges him to try and win the Kingdom from her fair and square in a democratic election. Koopa gets goaded into accepting the dare then panics, knowing very well that he could never battle the popular Princess with his nasty reputation. He takes a "nice guy" potion and transforms into a lovable humanitarian who charms the voters. // Koopa announces that he is giving up being bad for good! He can't compete with the cleverness of the Princess and the Mario Brothers and as a gift of apology for his past behavior he gives The Princess the keys to Kastle Koopa! Delighted at the prospect of turning the Kastle into a shelter for homeless mushrooms, the Princess and the suspicious Mario Brothers go to inspect the palace, only to find out too late that they have been pawns in Koopa's plan to teach Cheatsy the sneaky benefits of double-crossing.
