Super Smash Bros. Ultimate will add spirits from Paper Mario: The Origami King soon, crossing over Nintendo's massive fighter with the company's latest Switch hit exclusive. Three spirits will be available to nab: Origami Peach, Mario's helper Olivia, and the game's villain Olly.

As revealed by the Japanese Twitter account for Smash Bros., the spirits will be available from Friday, August 28 until Tuesday, September 1.

There's already a Paper Mario spirit available in the game--although if past precedent stands, the fact that he's not included in this crossover is likely to spark rumors that the character will join the roster as a fighter.

Super Smash Bros. Ultimate's spirit board continues to be a home for many crossovers, having received spirits from Octopath Traveler, Cuphead, Warframe, Trials of Mana, and more. These are often limited-time events, though.

Super Smash Bros. Ultimate also recently added a new free stage, and has five more DLC fighters on the way, although they have not been unveiled yet.

Paper Mario: The Origami King earned an 8/10 in GameSpot's review.
