The frigid Forgo Horns are the fourth level of the Isolated Isles, which Kirby can explore to find Soul Pieces in the post-game of Kirby & The Forgotten Land. After defeating the final boss of Lab Discovera, Kirby will discover a mysterious new vortex at the top of Waddle Dee Town's Observation Tower. On the other side, Leongar's soul has been scattered throughout the six levels of the Isolated Isles, each of which is a challenge-mode combination of the overworld levels from the main game.
To rescue Leongar, Kirby and Elfilin will have to find at least 250 of the 300 Soul Pieces in Kirby & The Forgotten Land's Isolated Isles. However, there's a special figurine that Kirby can unlock by finding every single Soul Piece. There are 51 Soul Pieces hidden in Forgo Horns, and Elfilin will let Kirby know when he's found every Soul Piece in each area.

Forgo Horns has six areas, just like the other Isolated Isles levels in Kirby & The Forgotten Land. Each area is a dream version of the Winter Horns levels in Kirby TFL, and while they're shorter than the original levels, there are new puzzles and enemies that present an extra challenge. However, there are no hidden Waddle Dees or trophies to unlock, so Kirby can focus on collecting the Soul Pieces and rescuing Leongar from this strange dream realm.

The other five are waiting in the sixth area, but Kirby will have to defeat Phantom King Dedede to get them, and this fight is much tougher than the last battle with His Royal Nemesis.
