This article is about the monster. For the boss, see Mega Fatty.

The Fatty is occasionally found in The Basement. It walks slowly toward Isaac. Occasionally, if Isaac approaches one, it will stop to fart, which will push him back without dealing damage. This will also push away adjacent enemies to a lesser degree.

Half Sack [ edit | edit source ]

Half Sacks walk aimlessly around the room and leave Red Creep behind them.

Blubbers walk aimlessly around the room, randomly spewing a cluster of blood shots in all directions. When killed, there is a chance for it to become a Half Sack.

Pale Fatty [ edit | edit source ]

Pale Fatties can often be found in groups in The Depths. They behave like Fatties, but will also spit out 6 blood shots in all directions when farting. When killed, they have a chance to become Blubbers.

Fat Sack [ edit | edit source ]

They are commonly found in groups of one to three, and can also be found together with Pale Fatties. Fat Sacks leap offscreen and attempt to land on Isaac, shooting 6 bullets in all directions and leaving a puddle of Red Creep behind when it lands. Like Pale Fatties, they have a chance to turn into Blubbers when killed. These monsters behave very similar to Leapers.

Conjoined Fatty [ edit | edit source ]

Conjoined Fatties slowly walk towards Isaac and occasionally pause to fart out a line of damaging Green Creep. There is a chance that upon death, it will turn into a regular Fatty.

If killed while farting, the Creep line won't grow to its full length. It will instead stop spreading the instant the Conjoined Fatty is killed.

Blue Conjoined Fatty [ edit | edit source ]

Blue Conjoined Fatties slowly walk towards Isaac and occasionally fart out a homing Ipecac shot at Isaac. Unlike normal Conjoined Fatties, they won't turn into any kind of Fatty upon death.

Stoneys walk towards Isaac while blocking his shots. They stop and catch their breath after chasing Isaac for a few seconds. They do not do contact damage but will often push Isaac around. They are invincible, but die when the room is cleared, similar to the Death's Head enemies. Stoney are unlocked by defeating The Lamb for the first time.
