Peach's Parasol

Peach's Parasol (also called Peach's Umbrella) is what Princess Peach uses to defend herself and to glide in the air. In some games, it replaces and acts like how she uses her dress to do the same ability. Peach has been using this parasol ever since she was a baby.

Super Mario RPG: Legend of the Seven Stars
Her parasol first appears in Super Mario RPG: Legend of the Seven Stars, where it is a weapon able to be purchased from the shop in Seaside Town after Yaridovich is defeated, and colored blue. It has an attack power of 50 points, with a deviation of five points. Functionally, it is similar to a hammer, though instead of a second strike, it opens up when a timed hit is performed. She earlier uses a different, pink one to sneak out of Mushroom Castle; Mario is later shown using this one (or another of the same color) when Mallow is reunited with his mother and father.

Mario Party 3
Peach is seen using her parasol in the Mario Party 3 minigame Parasol Plummet.

Super Smash Bros. series
The parasol appears in Super Smash Bros. Melee, where she uses it in her up special move. She can glide in the air with it and hit opponents. It also appears in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS / Wii U, and Super Smash Bros. Ultimate, with the same function and its Super Paper Mario design. Peach also holds it in her up taunt and on-screen appearance as of Brawl, and in one of her victory poses in Ultimate. In the Subspace Emissary in Super Smash Bros. Brawl, Peach briefly carries the parasol around while strolling on the Halberd's deck, and later gives it to a just-restored Mr. Game & Watch shortly after scolding him.

In Super Smash Bros. Ultimate, Daisy uses a parasol identical to Peach's, albeit reused from Peach's alternate color in Super Smash Bros. for Nintendo 3DS / Wii U. She also holds it during her on-screen appearance.

Peach uses this parasol in Super Mario Sunshine to protect her from the dangerous heat, and she is also seen floating down with it in the ending.

Super Princess Peach
The parasol Peach uses in Super Princess Peach actually has a mind of its own. It is implied in-game that this parasol was once a human being until two sorcerers' magic transformed him. She can whack enemies with him and give him various upgrades. Perry can even eat enemies to refill the Vibe Gauge.
