Mickey Mouse Slaughterhouse

The Mickey Mouse Slaughterhouse is an underground skyscraper that first appears in Chapter 5 Part 2.

Overview
The Mickey Mouse Slaughterhouse was built by Mickey Mouse right after the old universe was destroyed and a new one was created. It serves as the primary tool to rule the Earth.

The MMS is the tallest building in the world, surpassing the Burj Khalifa (despite its similarity to the Burj Khalifa, the MMS is still the tallest building in the world) and the Target Café HQ. It is about a googolplex feet tall and it can hold up to said amount of people.

It is said that the MMS has 532 floors, but it's possible that there can be more than that. It also has said amount of basements.

At the top of the MMS is the Mickey Mouse Clubhouse, but with some changes.

According to Chase McFly, the pointy part of the MMS is at the bottom, making it impossible to enter, while the flat part is at the top, to make room for the clubhouse.

Floor 533: Mickey's restaurant
Mickey Mouse has rebuilt his restaurant on this floor, after its previous version on floor 400 was destroyed by Baldi. Strangely, this floor is located between floor 2 and 1.

Floor 532: Mickey Mouse Clubhouse
Floor 532, at the top of the MMS, is the Mickey Mouse Clubhouse, with the same stuff but there are some changes: there are torches everywhere, the cages are put to imprison certain people, skeletons are laid down on the floor, and there is a pit of lava. But the biggest change of all was the clubhouse's design; instead of the color it used to have, the clubhouse's walls, floor and ceiling's paint has become pale and there are lots of ripped wallpapers inside.

Floor 531: Concentration camp
Mickey Mouse has built a concentration camp on this floor for whoever he wants to capture. Asgeir has been held captive in the concentration camp, and Ćąłęńą has escaped from the camp.

Floor 500: Part 27 replica
This floor resembles an outdoor environment, looking like Part 27. It's filled with tourists, mainly from Belarus, who think it's the real part 27.

There's also a giant Venus Flytrap on floor 500, eating humans and burping out food it doesn't like.

The turkeys from this floor have founded a city in Iceland called Türkeytöwn.

Floor 498: Giant chocolate cup
Originally, the floor was a bathroom, but Mickey Mouse removed everything. This floor now has a giant cup filled with chocolate, leading to Iceland. The cup refills when there's chocolate missing from it, making the chocolate usable as a building material.
