For the item with a similar name, see The Mulligan.

Mulligans are enemies with tear-filled eyes and a bloated head that appear in Chapter 1. Mulligans are afraid of Isaac and will actively try to avoid him; their eyes widen and their speed increases when doing so. In their panicked state, they may stumble over spikes or into a fire.

Upon death, they can spawn several Flies, Attack Flies and, occasionally, a Pooter. Mulligans may self-detonate, indicated by them holding their breath and inflating; in addition to spawning flies as normal, it will also fire four shots in the cardinal directions and destroy nearby objects when doing so. Mulligans cannot deal contact damage to Isaac ( unless they are Champions.).

In later chapters, deformed variants of Mulligans will appear.

Chance to replace Mulligans

Mulligoons display a depressed appearance, but unlike Mulligans, they do not have tears in their eyes. Their skin is a darker shade and one eye appears to be missing. Much like Mulligans, they are afraid of Isaac and will run away from him, don’t deal contact damage, and can self-detonate. They release 4 projectiles in all diagonal directions and drop a Troll bomb on death. If they self-detonate, they release 8 projectiles in all directions rather than 4 in the ordinal directions in addition to dropping a Troll bomb.

Rare chance to replace Mulligans or Mulligoons

Mullibooms have a bomb wedged into their head. Instead of avoiding Isaac like all other Mulligan-types, they will charge at him and explode on contact, dealing half a heart of damage. They also explode immediately if they are killed, similar to Boom Flies. Make sure to keep a safe distance when delivering the final shot, and consider killing them next to a tinted rock or a wall that might be adjacent to a Secret Room.

Hives are Mulligan variants with a rotting head and no eyes. They can be found in Chapter 2 and Chapter 3. They behave similarly to Mulligans, including evading Isaac and spawning flies upon death. However, they also occasionally spit Attack Flies while running away from Isaac, and unlike Mulligans and Mulligoons, they can't self-detonate. Hives have higher health than Mulligans.

Nests are a new enemy variant in Rebirth. They are Mulligan variants that behave similarly to Hives, but they spit Spiders instead of Attack Flies. They spawn a Trite or a Big Spider upon death. Nests share the same high health as Hives.

Leper

Base HP	Stage HP

Entity ID
310.0

Found In

Lepers are a Mulligan variant introduced in Booster Pack #5. Lepers will normally chase Isaac, but they will run away upon getting hit. For every 15 damage they take, a chunk of their head, known as a Leper Flesh, will detach and start erratically chasing Isaac. Lepers deal contact damage if they are in this state or below. Lepers can naturally be found with some head chunks missing.

After being reduced to 15 health, Lepers will chase Isaac continuously, even when taking damage, leaving a trail of damaging Red Creep. Upon death, they leave behind one Leper Flesh and a Grey-coloured Gusher.

Found In

Bouncers behave like regular Mulligans, however after some time or when they're close to death, their head inflates and they start chasing Isaac. If they die or touch him in this state, they explode into a spectacle of blood shots with some lingering in the air before dropping down. If they are killed before they enter this hostile form they release 4 blood shots in all diagonal directions.

They can also reflect shots in their inflated state.

Trivia

• The Mulligan, Mulligoon, Hive, and Swarmer are all the same monster in stages of decay and infestation.
• In the original Binding of Isaac, when a Mulligan self-detonated, the explosion would not break rocks.
• Mulligans will start running in random directions instead of directly away from Isaac if he stays close to them for long enough. This behavior also applies to Small Baby Long Legs.
• Mulligans, Mulligoons, and Mullibooms can be manipulated into destroying tinted rocks and opening Secret Room doors. Mulligoons and Mullibooms only need to be positioned next to the item before being killed, while Mulligans have to be pushed into a corner where the item is and baited into self-detonating. Example
• In the game's files, there is an unused Mulliboom self-detonation animation, an unused graphic of a Hive with a Mulligoon's face, and an unused graphic of the Drowned Hive with a blue-tinted Mulligoon's face.
• Drowned Hives, along with Drowned Chargers (name of Drowned Charger wasn't revealed), were revealed for Afterbirth in this official Binding of Isaac post.
• A leper is a person who suffers from leprosy, which is a contagious disease that causes discoloration and lumping on the skin plus disfigurement and deformities.

Bugs

Bug!	If a Mulligan or a Mulligoon is killed before the spawning period is finished (before they move), it will count as a self-detonation.

Bug!	If a Nest is killed in the Burning Basement, it has a chance to spawn a Flaming Hopper.

Bug!	Rarely if you kill a Drowned Hive before their spawn period is finished (before they move), it will shoot 4 projectiles in ordinal directions but the monster won't explode.
