Shiny Mushroom

Shiny Mushrooms are items in Paper Mario: Sticker Star and Paper Mario: The Origami King.

In Paper Mario: Sticker Star, Shiny Mushrooms appear as stickers and can be bought for 30 coins in Decalburg, Outlook Point, and Shaved-Ice Cave, and found in Whammino Mountain and Rumble Volcano. They normally heal 40 HP, however pressing right before Mario uses it will restore 60 HP.

In Paper Mario: The Origami King, they can be bought for 300 coins in Toad Town, Shogun Studios, and Diamond Island, or in threes as a Shiny Mushroom 3-Pack for 840 coins at Shroom City and Diamond Island. Using one in this game restores 100 HP.
