FNaF Multiverse RP: How to Get The Undercover Poster Badge and Classic Mangle Morph

The Undercover Poster is one of the harder badges to stumble into by accident in FNaF Multiverse RP, because the room it lives in has no visible door. It sits behind a Mangle poster in Kids’ Cove on the FNaF 1 map, and the only way in is to shrink yourself down with a small morph and walk straight through the wall. Claiming it also unlocks the Classic Mangle morph.

Quick answer: Teleport to the FNaF 1 map, equip a small morph such as Bucket Bob, walk through the wall behind the Mangle poster in Kids’ Cove, and touch the workbench inside the hidden room to be awarded the badge.

The Undercover Poster badge requirements

Everything about this badge is fixed. There is no timed window, no boss, and no item to collect beforehand. You only need to be on the correct map with a character small enough to clip past the wall geometry.

Detail	Value
Badge name	The Undercover Poster
Rarity	2.0% (Insane)
Map	FNaF 1
Area	Kids’ Cove, at the Mangle poster on the wall
Requirement	A small morph, such as Bucket Bob
Trigger	Touching the workbench inside the hidden room
Reward	Classic Mangle morph

The badge description in game frames the room as part of the story rather than a bug in the wall:

during a birthday party, someone put up a Mangle poster in Kids’ Cove, but that poster was hiding a fan who was painting Foxy’s body to turn him into the classic version of Mangle. She claimed that the female version of Foxy was missing after the Bite of ’87 occurred.

How to get The Undercover Poster badge in FNaF Multiverse RP

Open the teleport menu and select the FNaF 1 map. The poster only exists here, so attempting this from FNaF 2 or any other map will not work.

Enter the pizzeria and make your way to Kids’ Cove. Look along the walls for the Mangle poster, which is the marker for the hidden room behind it.

Open the character menu and equip a small morph. Bucket Bob, listed under the FNaF 6 morphs, is small enough to pass through the gap in the wall.

Selecting the Bucket Bob morph in the character menu before entering the hidden room — Bucket Bob, found under the FNaF 6 morphs, shrinks your character enough to slip behind the poster.

Walk into the wall directly behind the poster. As the small morph, you pass through instead of being blocked, and you end up in a narrow hidden room.

Touch the workbench inside the room. The badge is awarded on contact, so you do not need to interact with anything else in there.

How to confirm the badge unlocked

A “Badge Awarded” notification appears on screen the moment you touch the table. After that, Classic Mangle shows up as a selectable option in the morph menu, which is the second confirmation that it registered.

If nothing happens, the cause is almost always one of three things. You are on the wrong map, you are still in a full-size character and the wall is stopping you, or you reached the room but never made contact with the workbench. Swapping back to Bucket Bob and walking directly into the table resolves all three.

What the Classic Mangle morph does

Classic Mangle comes with its own control panel rather than a single idle animation. The buttons cover posing, facial states, and audio, and they can be combined, so you can hold a pose with black eyes and radio static running at the same time.

The Classic Mangle morph in game with its pose, eye, and audio toggles on screen — The Classic Mangle morph and its control buttons, unlocked by the badge.

Control	Effect
OFFICE POSE	Sets the morph into its office pose
SCARE	Plays the jumpscare animation
JAW OPEN	Opens the jaw
EYES CLOSED	Closes the eyes
HIDE EYELIDS	Removes the eyelids
BLACK EYES	Switches to blacked-out eyes
ENDO PIPES	Toggles the exposed endoskeleton pipes
RADIO	Toggles the radio static audio
MOVEMENT SOUND	Toggles the movement audio

Once the badge is on your account, the morph stays available, so you can drop Bucket Bob and switch to Classic Mangle straight away in the same session.
