Vibe Scepter
The Vibe Scepter is a very important item found in Super Princess Peach. It could be considered that game's main artifact, and it affects the enemies' Vibes.
Its legend begins when Bowser, stationed at his summer villa on Vibe Island, discovers its mystic power and ability to drive people's emotions to an insane point. He sends out Army Hammer Bro. (with some of his lessers) to find the ominous wand. Unfortunately for Mario, who was Bowser's main victim in this escapade, Army Hammer Bro came back from his conquest successfully. The Koopa Troop then decided to trust a Goomba, who used to live in the Mushroom Kingdom, with the responsibility of storming the castle. The Goomba made it in successfully and wreaked havoc as he was told to, letting Bowser's Hammer Bros. successfully kidnap Mario, Luigi, and several Toads.
Bowser was delighted when Army Hammer Bro came back with good news, but the Goomba who did the work was acting odd (or so said Army Hammer Bro). This Goomba, affected by the Joy vibe, foolishly swung the Scepter around, causing the same havoc in Bowser's Villa and Vibe Island that he did in Peach's Castle.
Back at the castle, Toadsworth, Peach and a Toad had just returned from a walk to find the castle in chaos. During a recap of what had been going on, Princess Peach made the fateful decision of finding the Mario Bros. herself. Toadsworth (leaving the job of keeping things in the castle running smoothly to Toad) then chased after her, eventually agreeing with her decision and arming her with Perry.
Peach encountered several enemies affected by the Vibe Scepter on her adventure, but did not directly see it until the final fight with Bowser. During the first part of her battle with the Koopa King, he used it to power himself up with several different Vibes. After Bowser was defeated for good, the legendary Scepter was secured and everyone was relieved of their wild emotions. It is unknown what happened to the Vibe Scepter after the game, although the ending sequence seems to suggest that it is actually a vibrator, as it is quoted as saying "The Vibe Scepter has strange and mysterious powers, that's for sure... Maybe... Just maybe... The Vibe Scepter is hidden away in your house somewhere... Has your mom been laughing happily a lot?".
