The Sparky Sticker is an item in Mario Party 4, and was Waluigi's favorite item. The item is a sticker with the image of an Amp on it. The item is used by placing the sticker on a space. Any character stepping on the sticker would get shocked, causing them to lose ten coins, as well as any effects of a Mini Mushroom or Mega Mushroom.
The placement method for the Sparky Sticker would later be used in the following three Mario Party games (Mario Party 5, Mario Party 6, and Mario Party 7), where characters can throw/place orbs on spaces and characters that touch (and/or pass through in Mario Party 6 and Mario Party 7's case) will feel the effects of that orb. This has a similar function to placing red orb on a Blue Space or Red Space and making it into a roadblock. However, this is the only item that can be placed on the space the player is standing on, as opposed to Blue Spaces or Red Spaces ahead of the player.
