The Blob in FaultyMarkus Games' Roblox survival title Fatal Floors is a Danger Level 1 entity that wanders slowly across early corridors. While its fleshy mass inflicts continuous damage, slow effects, and reduced jump height upon contact, its exposed rib cages have solid collision and deal zero damage, allowing players to vault directly over it in narrow hallways.

Fatal Floors Blob Stats and Spawns

The Blob was the very first entity introduced to Fatal Floors and serves as the baseline obstacle on early exploration floors. Unlike pursuit monsters such as the Weatherman or the Cave-Crawler, the Blob never targets players directly and cannot initiate a chase.

Entity NameBlob
Danger LevelLevel 1
Entity BehaviorHazard / Roaming (Aimless)
Chase CapabilityNone (Cannot chase)
Confirmed Floor SpawnsGuaranteed on Floors 1, 3, 4, 5, 6, and 7 (Floor 2 skips Level 1 spawns)
Duplicate SpawnsSpawns multiple instances on Floor 11 and above
Associated BadgeGross Remains (Encounter the Blob)
Collision VulnerabilityRed flesh, dark spots, and eyes deal ticking contact damage
Safe SurfaceExposed white rib structures on top

The Blob spawns primarily in the light gray corridors of the Facility floor type and the hallways of the Mansion. In higher runs beginning at Floor 11, room layouts can generate duplicate Blobs within the same sector.

Contact Damage and Movement Debuffs

The Blob emits faint squelching, tentacle-like movements paired with a low, dull moan. It wanders along predefined pathing nodes without deviating to pursue employees. However, blundering into its hitbox causes immediate consequences:

  1. Rapid Damage: Players caught in the Blob lose health rapidly over time (documented by community logs at roughly 30 HP per second, or ticking 10 damage increments).
  2. Movement Speed Reduction: Walking into the Blob significantly slows forward velocity, making it hard to walk straight through.
  3. Decreased Jump Height: While standing in the red mass, player jump power drops, preventing standard obstacle clearance.
  4. Screen Vignette: The player screen gradually shifts to an intense red tint for as long as contact is maintained.

If you step onto the Blob's flesh, do not attempt to jump up onto its ribs. Because the debuff suppresses jump height while you are inside the hitbox, you will not clear the height requirement to reach the ribs; your priority must be moving backward or sidestepping out of the mass.

How to Bypass the Blob: Ribs vs. Teeth

A common point of confusion among new players is whether the white structures along the Blob's back are teeth or rib bones. Developer FaultyMarkus confirmed via official communication that these structures are exposed ribs.

Each Blob model features three distinct rib clusters (with six rib segments per cage) separated across its body. These ribs possess solid physical collision and deal no damage.

  • Stepping Over Narrow Hallways: In tight Facility corridors such as Parallel Corridors or narrow Mansion bedrooms where a Blob blocks the entire width, sprint and leap directly onto one of the white rib clusters. From there, you can jump across to safe flooring on the other side.
  • Waiting for Movement: If you are low on health or carrying heavy valuables like ore backpacks, you can stop outside its path. Because the Blob moves along set pathing lines, it will eventually creep past corridor junctions.
  • Door Manipulation: In the Mansion and elevator entryways, closing a door or gate right before the Blob crosses the threshold forces its pathfinding to reverse direction, provided the door hitbox does not clip directly through its center.

Blob Research Lore and In-Game Origins

Completing research on the Blob unlocks the official internal record within the Facility logs:

"The company's most embarrassing experiment, we tried fusing 3 different subjects into one, but instead we created an abomination that is completely incompetent and is in constant agony. They are extremely resilient and our attempts at neutralizing these blobs were all unsuccessful, so we just kept them in vats in the facility."

The entity's lore explains why it wanders aimlessly rather than hunting: it remains in constant physical agony following a botched three-subject fusion test. When an emergency power overload in the Greenhouse triggered facility-wide security failures and mass evacuations, containment vats ruptured, releasing the surviving specimens across the corridors alongside escaped Cave-Crawlers and Bone Hounds.

Frequently Asked Questions

Can the Blob chase you into the elevator?

No. The Blob does not possess an aggro or chase state. However, because it wanders along pathfinding target nodes, it can gradually glide into the elevator room if gates are left open and its route leads into the center chamber.

How do you unlock the Gross Remains achievement?

You unlock the Gross Remains badge by getting directly adjacent to the Blob or by landing safely on top of its white ribs. Taking damage is not required to register the encounter.

What inspired the creation of the Blob in Fatal Floors?

According to official game trivia and developer notes, the Blob was inspired by the Hygrodere slime entity from the cooperative survival horror game Lethal Company.
