Kirby and the Forgotten Land (Hoshi no Kirby: Discovery in Japan) is a 3D platformer in the Kirby series, released for Nintendo Switch on March 25, 2022. It is the first fully 3D platformer and the first mainstream 3D game in the series.
One day, a bunch of dimensional rifts opened up above Pop Star. These holes in the space-time continuum sucked up many inhabitants, including Kirby and the Waddle Dees. Washing up on a shore in this strange new world, he finds that the Waddle Dees and a floating being called Elfilin have been captured by a team of terrifying anthropomorphic animals known as the Beast Pack. Kirby saves Elfilin and together they work to free the Waddle Dees.
Eventually, it is revealed that Elfilin is the "good" half of a being known as Fecto Elfilis, an entity that invaded this land years ago but was captured by scientists and experimented upon to take advantage of its reality-warping powers. An accident split Elfilis into Elfilin and Fecto Forgo, which now controls the Beast Pack and has been capturing Waddle Dees to syphon energy from. Kirby meddles in Forgo's plans, causing it to take matters into their own hands and eventually absorbing Elfilin to restore themselves to Fecto Elfilis. Kirby beats this chaotic beast and extracts his new friend, causing Elfilis to become unstable. Kirby inhales a semi-truck and crashes an asteroid into Elfilis, destroying it and restoring the Beast Pack and the rest of the world, as well as returning himself and the displaced inhabitants to Pop Star.
