Amniotic Sacs are obstacles encountered in the 
Womb. They can contain either a 
Neonate, a 
Baby, an 
Embryo, or be completely empty, depending on the appearance of its contents. Amniotic Sacs can be destroyed in a single hit from Isaac's attacks, and will leave a tiny puddle of damaging yellow creep under itself while releasing their contents.
- Amniotic Sacs are treated more as enemies rather than obstacles, as they will be targeted by familiars and homing tears, and can be destroyed by effects that would not normally do so for other destructible obstacles (ex. contact damage from
Aries).
- Amniotic sacs will not deal contact damage, cannot be flown over, and do not need to be destroyed to clear the room. If the room is cleared and left, any remaining Amniotic Sacs will appear destroyed upon re-entering the room.
Notes
- Amniotic Sacs can be destroyed by the laser attack from
Onlookers.
Miscarriage
Miscarriages are variants of Amniotic Sacs, encountered exclusively in the 
Corpse. When destroyed, it leaves a tiny puddle of damaging red creep under itself, and may contain either a 
Wrinkly Baby, an 
Unborn, several 
Small Maggots, or be completely empty, depending on the appearance of its contents.
Trivia
- An amniotic sac is a layer of membranes which contains a developing fetus inside amniotic fluid.
- A miscarriage is the death of a developing fetus before it is able to survive independently from the womb.
