Subscribe Rooms

Subscribe Rooms are a somewhat common anomaly. Though they vary in appearance and ways to access them they all have one thing in common, that is a mysterious one-word message which simply states “Subscribe.” It is currently unknown what Nintendo meant by this. They are seemingly inescapable once entered and the game must be reset for any progress to be made.

Aquarium Subscribe Room #1
This first subscribe room in the castle aquarium is found from BLJ-ing into the small aquarium in the Jolly Roger Bay room, and standing in a specific seemingly random spot. This causes Mario to play his teleport animation. Mario will then arrive in a small dark room filled with black bricks and red 3d text which spells "Subscribe".

Aquarium Subscribe Room #2
The second is found within the black square hole where the one up usually spawns. It features large chrome letters which spell out subscribe floating on life savers. It is possible to leave via the exit course button, or drowning. Underneath the letters is a deep pool of water which can be swam in.

Bob-Omb Battlefield Subscribe Room
The Subscribe Room in Bob-Omb Battlefield is not actually a room but instead a bunch of toy blocks found on top of the hill if Footrace With Koopa the Quick is selected. Other than selecting Footrace With Koopa the Quick, it is unknown what other steps must be taken to trigger the event.

Big Boo’s Haunt Subscribe Room
The Big Boo's Haunt subscribe is accessed by going to the often skipped library in big boo’s haunt, and standing in the left corner. A jingle will play and then the player must move Mario to the right corner to teleport to the room. The room starts off as a bending path of bookshelves. In some copies it may even be a maze-like in structure. At the end of the path are bouncing white letters which spell out subscribe. Unlike other subscribe rooms the player can die here, by jumping off the ledge. They will respawn in the Castle Courtyard.

Hazy Maze Cave Subscribe Room
The Hazy Maze Cave subscribe room is found within the large pit in the room with rolling rocks. Instead of dying like normal Mario will fall into a small room. Unlike most others it contains an NPC, in the form of a variation of the Bob-omb Buddy with black shoes and a black fuse. When talked to, the screen zooms out and big letters written in the typical NPC text font will display one by one spelling out “subscribe.” When the player pauses the game, the title’s level will be changed to “Subscribe Maze Cave,” the mission’s title will be changed to “Footrace With Koopa The Quick,” and the exit course button will read “subscribe” though it still functions as usual.

Tiny-Huge Island Subscribe Room
The Tiny-Huge Island subscribe room is found via entering the small normally inaccessible hole in which the black cannon balls spawn. When entered there are minecart tracks where the black cannon balls roll. There is a Bob-omb Buddy surrounded by a ring of coins. When talked to it will say the same dialogue that is stated when booting up Bob-omb Battlefield for the first time. There is a square hole here which when entered leads to an inescapable room with a black slope where cannonballs fall on Mario, causing him great distress. It is impossible to escape without resetting the game.

Snowman’s Land Subscribe Room
Snowman’s Land's subscribe room features the subscribe letters frozen in ice. Every time Mario enters the igloo it has a slim chance of spawning. The room is small and sloped in, and inescapable without restarting the console. One of the most malicious subscribe rooms since it can stop the player from getting the Vanish Cap star.

Tick Tock Clock Subscribe Room
The Tick Tock Clock subscribe room features the letters on top of slowly spinning  gears. It is accessed through standing above a few small gears near the start of the level. Mario will teleport into the subscribe room. It has a ledge underneath the letters so it is possible for Mario to escape to the castle by losing a life.

Wing Mario Over the Rainbow Subscribe Room
Sometimes accessed through entering the Wing Mario Over the Rainbow Stage this is possibly the most ominous subscribe room. Mario spawns in a dark checkerboard room, with a small spotlight on him, the default Bob-omb Battlefield text is said as Mario must run towards a distorted 3d flicker image of him. As Mario approaches the head a signpost spawns beneath the head. It reads:

“YOU ARE TRYING TO OUTRUN THE GAME

IT CAN ADAPT.

IT CAN IMPROVE.

IT WILL FIND A WAY TO GET YOU.”

Afterwards Mario is teleported into a void of floating pre-rendered images of his own head. Then to a gray faded room with clouds and an eerie music box song. To escape, Mario must jump off the ledge and respawn above Peach's castle and fall into the small pond.
