Myiasis
Myiasis are enemies found in Scarred Womb that will float erratically towards Isaac while staying a set distance away from him. When in range and lined up diagonally with Isaac, they will launch a 
Chubber-like projectile towards him, which will fly diagonally off-screen before wrapping around again continuously from random positions. The empty body will float slowly towards Isaac until the Chubber flies into it, after which it will catch the projectile and restart the cycle. An empty Myiasis body can catch any flying Chubber projectile shot from another Myasis and is not restricted to the one it fired out.
Myiasis can spawn as empty bodies without the Chubber and will only float slowly towards Isaac. If encountered in a room with other Myasis, they can still catch Chubber projectiles, and will behave as usual if done so.
Destroying a Myasis body will kill the Chubber projectile it spawned with, regardless of what body that projectile is currently inhabiting.
Notes
- If 2 Chubber projectiles fly into the same empty Myiasis body at the same time, only one will remain in the body with the other 'disappearing'. It is unsure if this is intentional or a bug.
Trivia
- They are referred to as "Blubber" in file names, however
Blubber is already the name of a vanilla enemy.
