Unused Content
As with any project, not everything can make the final release, and a few things have to be left on the cutting room floor. Here's a few of those that were lost but not forgotten!
Some of this content may be implemented in the future, according to the developers. They have plans for some of these concepts to be actualized in game, whenever that will be! Everything here has a possibility of being added!
For more sprites and concept art of enemies that have gone unused, see Yeast.
Enemies
Angler
A skeletal head on a spinal cord, with a lightbulb protruding from its forehead, resembling an anglerfish (hence the name). Its color scheme could suggest it being a Corpse enemy.
Baddyboom
An enemy that appears to be a variant of Blastcore.
Blowhog
A monster that somewhat resembles Dogmeat. Considering its name and some frames in its spritesheet, it would have blown a gust of air for its attack.
Blue Conjoined Maw
An unfinished Chest enemy, which we have footage of before it was removed, the smaller head would shoot multiple times at isaac while the big head would shoot a big purple tear with 3 flies circling around it, once the tear dropped the flies would start chasing Isaac.
Brandon
An enemy, likely for Corpse, whose animation files seem to indicate attacks that would consist of spitting its own teeth at the player. Brandon was given a new sprite in the V2.8 update, but has still not yet been implemented.
Calsiketic
An enemy that originates from the mod Guwah Greatures. It is unknown if it will ever be implemented into Fiend Folio.
Cochlea
An enemy that presumably could be encountered in either Womb or Utero.
Color Red
A spritesheet of an unknown entity or an effect.
Copper Bombgagger
It appears that the developers once planned to make an adjustment to vanilla Bombgaggers and give them the ability to spawn copper variants of Giga Bombs. This would also mean the addition of such bombs as pickups.
Cyan Moter
A giant cyan fly with a tiny fly attached to it. Its behavior is unknown.
Drainer
This enemy seems to be a posthumous variant of Warhead, and can be spawned in-game. It behaves similarly to its normal counterpart but moves slower, leaves a thin trail of yellow, damaging creep and upon death, spawns a pool of yellow creep and releases four projectiles in cardinal directions.
Fiend's Gang
These are old sprites of the various members of Fiend's gang, taken from the original reference sheet. They are as follows:
- Fiend (Using his original Devil's Harvest sprite)
- Friend
- Fend
- Frond
- Fient
- China
- Mi
Secret Imp
There is a sprite of a green character found in the sounds file. Her name is Secret and not much is known about her.
Fly Eyes
An Attack Fly with two tiny eyes.
Fogspawn
An enemy that bears strong resemblance to Dusk. A red-colored version can also be found in the files, implying it would have been found in both Mausoleum and Gehenna.
Fount
A Frog variant with a blue palette. Can be spawned in the game but has no AI.
Generous Snagger
What appears to be a Snagger with a Grab Bag on its head, is probably an upgraded variant of a regular Snagger. Its behavior is unknown.
Gishle
An enemy that looks like it belongs in Dank Depths. It can be spawned in the game, however, it has no AI and just slides across the room. Its behavior is unknown.
Kawasaki
Some sort of brain-like enemy. It is unknown what it would do, but of note is that its "skin" and "brain" are different parts of the same spritesheet.
Keeper Heads
Keeper-like heads based on Gluttony, Pride, and Wrath respectively.
In the Halloween teaser, the Gluttony head's behavior was revealed, and has been named "Devourer".
Kriegsheld
An enemy that has been impaled on a set of bones.
Laideronette
An enemy that appears as a tall, white pillar in the shape of a human arm. Confirmed to be in the next update.
Lemonhead
A lemon-shaped head of a Gaper. Its behavior is unknown.
Level 0 Fly
A fly variant that appears all glitched and corrupted. It is currently unknown what purpose would it serve.
Level Poo Fly
Another fly variant. Would have been likely appeared in Dross.
Malicispirit
Most likely a Flickerspirit variant. It is unknown what type of boost it would apply, but its color scheme could suggest it being a Gehenna, Sheol, or Dark Room enemy.
Matchstick
A Round Worm variant that could appear in Burning Basement. Presumably, it would have some sort of flame-based attack, but its behavior is unknown.
- In the file with the death notes, a burning version of Roundy can also be found.
Meat, Slack, and Fiend Morsel
A Globin, Gish, and Fiend variants of Morsel can be found in the mod files. Their behavior is unknown.
Meatsack
A very tall enemy that could appear in Gehenna, due to being in a similar style as Tagbag. Possibly a Hooligan variant.
Mite
A tiny bee enemy that can be spawned in the game but possesses no AI.
Mom
An enemy (or maybe a boss?) that appears to be a giant version of a Frog.
New Year
A cultist-like enemy that resembles the Blood Cultists from the Excelsior cover art.
Is confirmed by Sin on Discord to be added in an update and a video was posted to the Discord showing possible gameplay for the New Year, with its attack being similar to an Alderman's.
Puffball
A stationary enemy that will be coming in the next update.
Red Weaver
A Weaver tinted red. Its behavior is unknown, but probably has something to do with Boils, as some Boil-resembling sprites also appear in the spritesheet.
Rook
What seems to be a fusion of Sniffle and Knight, which would make it a rather difficult enemy. It can be spawned in the game, but has no AI.
Smelly
This enemy seems to be a corn variant of Dung. It would most likely have some sort of creep-based augmentation, but the true nature of its behavior is a mystery.
Snip
A monster that would probably have appeared in Scarred Womb. Its behavior is unknown.
Solid Serve and Dank Serve
Apparently, two more variants of Soft Serve were planned, based on Brown Poop and Tar, respectively. The nature of their augmentation is a mystery, however.
Soul Spooter
A Spooter variant that seems to be a Soul Sucker counterpart.
Its behavior was revealed in the Halloween teaser.
Spicy Load
Apparently, a Red Poop version of Load was also planned. Its behavior is unknown.
Spire
A presumably stationary, psionic enemy that would be found in Sheol.
Split Ear
An enemy that appears as a giant severed human ear.
Carrion Worm
A round worm like enemy. Originally uploaded by Ferrium in the Fiend Folio Cornmunity Discord.[1]
Stone Wimpy
A Wimpy variant of Stoney Slammer. It probably would create smaller rock waves and make shorter but more frequent jumps.
Strand
An enemy that looks to be a mix between Slinger and a Weaver. In the files, an alternative version of this enemy can be found, that resembles Slinger even more.
Toad
A Slammer variant with yellow eyes and warty skin, possibly hence its name.
Writhe
A crawling enemy, most likely designed for Ashpit. It possesses two variants - normal and ignited, which would suggest it having the ability to ignite from fire, just like Crucible.
Bosses
Heiress
A Boss that appears to be the posthumous version of Honeydrop. Unlike most other unused enemies and bosses, Heiress can be spawned in game through the Debug Console. Its attacks consist of:
- Constantly leaving a trail of slowing, white creep.
- Slamming the ground, spawning three Dart Flies and a random bee enemy (It can be either Hover, Homer, Stingler or Honey Eye)
- Slamming the ground, releasing three rings of projectiles, one after another: a ring of blood shots, ring of bones and a ring of both blood shots and bones.
After being dropped down to about 50% of its health, it loses its skull, spawning three Dart Flies, two Spiders and scattering a couple of bone projectiles around. While in this phase, its creep changes to a red, damaging type and its attacks change to:
- Slamming the ground, creating two rings of blood shots, along with occassional bone projectiles and six large blood shots in between.
- Coughing up two spiders and one from following:
- a One Tooth;
- two Milk Teeth;
- two Moters;
- three Suckers;
- a Boom Fly;
- three Pooters;
- two Spooters;
Bella and Queeny
Hidden in the files is a variant of Bella that would have likely been paired up with Heiress, along with an animation of Heiress' skull getting wrapped up and turning into a bug, likely the second phase of the fight.
Champions
Four unused champion versions of bosses can be found in the files. These champions are:
- Red Big Horn
- Pink Rag Mega
- Black Sisters Vis
- Smokey Griddle Horn
Grid Entities
Beartrap
A special type of obstacle that could immobilize the player or maybe the enemies.
Ectoplasm
A poop variant that would probably appear in Depths.
Harming Poop
Another poop variant that seems to be a hostile version of the Charming Poop.
Soft Poop
Yet another poop variant. Might be related to enemies like Soft Serve.
Totems and Switches
A set of grid entities that would work together to create new types of puzzles.
Their function was revealed in the Thanksgiving teaser.

Pickups
Battleship
A piece from the board game of the same name, although it ironically resembles the Aircraft Carrier more than the actual Battleship. Its effect is unknown.
Blood Bags
Made as a form of joke. Likely they would spawn Black or Eternal heart pickups respectively.
Chess Pieces
Fool's Gold Heart / Clot
A heart pickup with an unknown effect. It also has its own Sumptorium Clot.
From the name and sprites, it can be assumed that they function like Gold Hearts that drop Cursed Pennies when broken
Leaky Hearts
Leaky versions of the Red, Rotten, Morbid, and Broken Hearts. Likely were new types of heart containers, as they don't seem to be Bone Heart compatible.
Game Piece
A figure resembling the player pieces used in board games such as Sorry. Despite going unused, this sprite is used to represent randomly-spawning objects in Basement Renovator.
Platinum Penny
A very shiny, platinum-made penny that would have assumed to have been very rare, its true function is still unknown however, but one could suggest it may be a Dime variant of the Golden Penny.
Triple Penny
A pile of 3 pennies that, unsurprisingly, would have given 3 pennies when picked up.
Soul of Fortune Teller
A Soul Stone in the shape of a fortune cookie.
Soul of Friend
A Soul Stone in the shape of a bullet.
Soul of Slippy
Unused Soul Stone for Slippy.
Ticket to Ride Cards
Cards based on the board game "Ticket to Ride".
Unknown Yu-Gi-Oh! Cards
Two unknown Yu-Gi-Oh! cards. The one on the right possibly based on the card Mystical Space Typhoon.
Unknown Playing Cards
Two unknown Playing Cards Possibly the King of Clubs and King of Diamonds respectively, as the red card holding an axe is similar to the King of Diamonds in design.
Miscellaneous Unknown Cards
Several unknown cards, including a Pokemon card.
According to Erfly, the second card from the left is the "Ace of Pills", likely an early design for the Ace of Cups.[2]
Unused Disc
A pickup that looks like a Trial Disc. Its color is similar to the Angel Disc, but the center of the disc looks different, and the color is a slightly different shade. Its effect is unknown.
According to Erfly, the appearance apparently alludes to the Woke Records Logo, creators of the Walkwave music mod.[3]
Yeast Pills
Unused skins for pills, although the rightmost two strangely don't have small inventory sprites.
Machines and Beggars
Jukebox
An ordinary jukebox which possibly would've changed the music of the current room, considering the "change song" animation inside the files. Might have given trial discs when bombed.
Milk Machine
A machine with an unknown function.
Appears to be related to "Baphomet" from Maria's Imp gang canon, adapted from the character of the same name from The Devil's Harvest MOD.
Other
Unused Missing Link Variants
Missing Links have unused spritesheets for using Mutant Spider, Tractor Beam, and Tiny Planet.
Unused Challenge Unlocks
Achievement pages for the challenges Dad's Home+, The Real Jon, Dirty Bubble Challenge, Frog Mode, Hands On, and Isaac Rebuilt, respectively. Likely unused because the current modding API does not support unlockable challenges yet.
Crystal Caves
There are unused backdrop textures for a Crystal Caves subtheme.
Friendly Spoop
Within the files for the friendly Dips added in Fiend Folio is a spritesheet for friendly Spoops. May have been created when destroying the unused Ectoplasm grid objects with
Dirty Mind
Battie Medallion
A strange, abstract object found in the folder containing Battie's spritesheet. It appears similar to the Golden Medallion found in the
Dad's Home+ challenge.
Buster Medallion
A strange face found in Buster's spritesheet. It has been referred to by the developers as another medallion, similar to the Golden Medallion found in the
Dad's Home+ challenge.
Gold + Copper Bomb UI
Possible appearance that the bomb counter could take if the player has any Copper Bombs along with having a Golden Bomb.
