In Kirby's Epic Yarn, Butter Building makes a cameo appearance as a type of fabric inspired from the view from the top of the building. While the pattern seems to be original, it seems to be based on the original NES version, which had a similar background in certain levels. In addition, a piano rendition of the theme returns for Patch Land's Tempest Towers.
Kirby is seen casually strolling across one of the high-up parts of the tower. Just then, a Poppy Bros. Sr. comes along and knocks him to the edge of the platform. As Kirby struggles to get back up, the Poppy Bros. Sr. throws a bomb on his head and hops away. The bomb detonates seconds later.
This intro is almost the same in Kirby: Nightmare in Dream Land, the only difference being that Kirby frantically looks around puzzled before the bomb goes off, whereas the original had Kirby slowly turn upwards before it's too late.
Butter Building consists of six normal stages. It is a large, tall tower reaching up very high through the sky. It is constructed in the middle of a forest clearing and is a huge cylindrical burgundy and yellow building. Kirby starts off at the base of the tower and must work his way up to the very top. In the remake of Kirby's Adventure, the building is changed from a grand, gilded castle to a ruined, crumbling tower. In Kirby: Nightmare in Dream Land the building has small, unfinished towers at its base, and there are holes covered with wire grating on the decaying walls, signifying that the tower was never fully built or is now falling apart. At the very top of the tower, Mr. Shine & Mr. Bright await Kirby.
Stage 1: A couple of rooms after Mr. Tick-Tock, it should be in plain sight. Head down the pit to the right and destroy the Star Blocks obscuring a door. Activate the Bomb Block chain, revealing another door.
Stage 6: Outside of the tower, there are many platforms (clouds in Kirby's Adventure). Climb up until a cluster of Star Blocks on the tower is visible. Break them to reveal a door. Activate the Bomb Block chain, but act quickly in order to reach the door.
The name "Butter Building" likely comes from the structure's yellow color in the original game. This is untrue in the remake, because it is now purple and maroon rather than bright yellow.
In Kirby's Adventure, Butter Building had some stages where Kirby would stand outside of the building and walk around it, making it appear almost 3D. In the remake, it was replaced by the standard level layout instead of the 3D-like feature.
Nightmare's theme (wizard form) sounds somewhat similar to the Butter Building theme; it may be a remix of that music.
A remix of Butter Building's theme is used for the Crane Fever sub-game.
