Name	Icon	Description
Heartbeat		Slowly chases Isaac, continuously producing sounds of a beating heart. Occasionally will puff up and slightly decrease its chasing speed. When puffed up, whenever it takes damage, it will scatter a couple of blood shots around. When it dies, while puffed up, it explodes into a large amount of blood shots.
Valvo		Wanders around the room. Upon being shot at, it has a chance to eject a massive amount of blood shots towards Isaac in a volley fashion. Upon death, it leaves a single, large blood projectile that falls onto ground afterwards.
Jammed		Actively avoids Isaac, periodically spawning Smidgens. On death, spawns a Hostlet.
Red Jammed		Actively avoids Isaac, periodically spawning Red Smidgens. On death, spawns a Red Hostlet.
Tittle		Floats around the room diagonally, bouncing off walls, invulnerable to damage. Occasionally opens up and fires a spread of two short-ranged projectiles towards Isaac. This is the only time when it can be damaged. Very low resistance to knockback.
Bola		Remains stationary, launching its head, attached to its base with a cord, towards Isaac. The head drifts towards Isaac for a while, while a bloody clot in one of Bola's eyes starts growing. After the clot is fully grown, it explodes into a volley of blood shots. If Isaac moves too far away from Bola, it retracts its head back. While its head is retracted, it cannot take damage.
Astroskull		Bounces around the room, immune to damage. Has a specific amount of Lil' Junkies orbiting around it. The Lil' Junkies will slowly increase and decrease their orbit radius in a pulsating manner. Dies upon clearing the room, along with any Lil' Junkies orbiting it.
Sagging Sucker		Follows Isaac, firing a large volley of blood shots downwards when lined up diagonally with him. The volley will cause the Sagging Sucker to be repelled in the opposite direction, and launching itself towards Isaac if he is above it.
Trickle		Bounces around the room. After taking enough damage, it produces a fart that heavily knocks Isaac back and then transforms into a Skittering Trickle. In this form it skitters quickly after Isaac, occasionally releasing a ring of eight blood projectiles. If killed in either form, it releases a ring of twelve blood projectiles.
Magleech		Roams around the room aimlessly. If it bumps into a wall, it will stick to it and begin to puff up. Shortly after, it will launch itself away from the wall with high speed, while scattering a large amount of bone projectiles in the opposite direction.
Retch		Crawls around the room aimlessly. Occasionally stops to create a small shower of orange projectiles that leave puddles of slowing creep. On death, creates a larger puddle of creep.
Bladder		Remains stationary, periodically spitting out a line of yellow creep, along with several shots towards Isaac. Bladder will attempt to predict Isaac's movement, trying to cut him off with its attack.
Minimoon		Bounces around the room. Occasionally will stop its regular movement and start orbiting another enemy in the room. After a while, it will stop orbiting and resume its normal behavior.
Peepling		Floats around the room. Occasionally creates an arc of five tears around itself and then sends them away, aiming at Isaac.
Onlooker		Remains stationary, producing a harmless, semi-transparent laser in a specified direction. When Isaacpasses through that laser, the Onlooker will change it to an opaque, harmful laser for a short while. Continues its behavior even after the room is cleared.
Utero Pillar		Remains stationary and invincible. When Isaac draws nearby, spews out 1-3 Organelles. Continues its behavior even after the room is cleared.
Organelle		Moves around by performing short dashes in random directions. When touched, bursts into blood shots that leave puddles of damaging creep. Touching it will deal contact damage.
Cordend		Floats in one place, remaining invulnerable. Occasionally, it will extend its both halves to two sides of the room, connecting them with a cord. The cord can be shot at, forcing Cordend to close prematurely. Eventually will close by itself. Dies upon clearing the room.
Artery		Remains stationary and invulnerable in the ground. Will periodically spawn Mobile Blood Cells or Spinning Blood Cells depending on the room. These Blood Cells will travel to the nearest Vein and enter it. Stays active even once the room is cleared.
Vein		Behaves identically to Arteries but acts as the exit point for Blood Cells to enter.
Peepee		Hops around, occasionally spitting a large blood projectile towards Isaac.
