One of the biggest surprises during the Super Smash Bros. Ultimate Nintendo Direct was the reveal that Piranha Plant will be an early purchase bonus for the highly-anticipated fighting game.

Memes and Waluigi jokes aside, those looking to pick up Smash Ultimate will want to be able to download this free new character. However, Piranha Plant will only be available to download for a limited time after players register their game.
