Dumplings are round enemies that fly around aimlessly and fart. They fart whenever Isaac gets close, upon taking damage, and upon death. Farts knock Isaac back and propel it forwards. Dumplings usually don't damage the player directly; instead, they knock other enemies into Isaac or push the player into spikes.
Skinlings are a pale variant of Dumplings. They behave similarly, but their farts are poisonous and can damage Isaac.
Scabs are a bloody variant of Dumplings that actively chase Isaac. They easily catch up to him by making quick, rapid dashes in his direction. When attacked, they fart, shoot 6 blood shots in all directions, and fly off in a random direction. Upon death they again fart and release 6 blood shots in all directions.
- Dumplings are a reference to some of Edmund McMillen's earlier games, which consists of events unfolding on a planet called Golgotha. A dumpling is a creature of this planet, starring in multiple games and having one of their own.
- According to Edmund McMillen's in-game description of Dumplings, they are creatures made of rotting flesh, that fly using high quantities of methane their rotting guts produce, hence why their only attack is a fart.
- Skinling is the name of the species of not only for the aforementioned Dumpling, but the species name for the Weltling and Kankerling. A common trait amongst these creatures is that they don't have muscle and rely on other methods for movement or survival.
