Entity #012, "Contagious Decal"

Description

Entity #012, dubbed the Contagious Decal, was a strange Roblox image asset first discovered in late 2015. Though uploaded under an untraceable user ID, its origins are unknown. The decal resembles a heavily compressed .jpeg of a hallway or tunnel, though color distortion and visual tearing make details unclear.

The asset would randomly appear in games without being manually inserted by developers. Once present, the image would embed itself into any nearby surfaces — often replacing textures on parts, UI elements, and even avatars. Once "infected," removing the asset was reportedly impossible without deleting the game file entirely.

Initial exposure to the decal appears harmless, but after several minutes of being loaded into a game, strange phenomena begin:

• Distorted whispers play through the game's audio channels, even when all scripts are disabled.
• The image becomes more pixelated with time, occasionally “shaking” or becoming overexposed during gameplay.
• Infected players report persistent sound loops and UI glitches, even when playing different games afterward.

The decal spreads through local file caching. Players who join an infected game will begin seeing the decal appear in unrelated places across other experiences, even offline. Some report decals spawning in Studio during development, overriding other textures.

Reports of the decal entering private inventories or being attached to previously safe assets have not been confirmed, though screenshots suggest it can "merge" with unrelated images.

Roblox removed the original asset in early 2016. However, community sightings persist in archived experiences, and attempts to inspect or re-upload associated image data tend to crash Roblox Studio.
