The stage is based on several areas from the Paper Mario series, and its layout shifts between three versions in a pop-up book style.
The starting variation is based on Hither Thither Hill from Paper Mario: Sticker Star. It features a windmill that will spin under a heavy player's weight and a pipe that pushes anyone standing on it into the air. Near the end of this variation a fan appears in the background and generates a strong wind which blows away several stage elements and pushes fighters to the right of the stage.
The second variation is based on the S.S. Flavion, a ship from Paper Mario: The Thousand-Year Door. The ship may be accompanied by a giant Blooper, a recurring boss in the series: it does not directly interact with the stage, but it does form waves in the water that can carry players. Another possible occurrence is the appearance of the Whale from the original Paper Mario, which raises the ship with water spouting from his blowhole. This stops the ship's rocking and carries it closer to the upper blast line.
The last variation is Bowser's Sky Castle from Paper Mario: Sticker Star, which features a large bust of Bowser's head plus two floating platforms that move up and down on either side. The head's eyes will occasionally glow to denote what it does next: Red means it will start spinning, making it hard to stand on, and white precedes the head's jaw clamping shut, which deals moderate damage and knockback to anyone inside it.
After a while, the scene switches back to Hither Thither Hill and the cycle repeats.
Hither Thither Hill comes from Paper Mario: Sticker Star. In that game, Mario had to use the Fan sticker to access the windmill since the sails were blocking its entrance. When he used the sticker, a cutscene played where several nearby obstacles were blown away. When used in battle, the Fan sticker would blow all enemies around.
The S.S. Flavion appeared in Paper Mario: The Thousand-Year Door, where it was the ship of Flavio. During Chapter 5, Mario and his party had to use it to sail to Keelhaul Key. After several days of sailing, they were ambushed by several Embers. The ship wrecked on Keelhaul Key, and its scraps were used to set up camp on the island.
Large Bloopers are recurring bosses in the Paper Mario series, most notably in the first three. The specific Blooper bears a strong resemblance to the one fought in The Thousand-Year Door.
The Whale from Paper Mario, who was used to take Mario to Lavalava Island, makes an appearance, using his water spout to lift the S.S. Flavion a notable distance above the water. The background is the same one from Riverside Station in Chapter 6.
Bowser's Sky Castle comes from Paper Mario: Sticker Star. Here, Mario and Kersti face off against Bowser in the final fight.
