Mama Guts

Mama Guts is a monster first added in the Wrath of the Lamb expansion, and also return in the Rebirth remake. They first appear in Chapter 4.

It appears as a large blob of internal organs, much larger than regular Guts.

Behavior

Instead of attaching to an object, they slowly move around the room, eventually firing 8 large blood shots. Killing it will cause it to split into 2 Guts.

Eternal Champion Behavior

It fires 8-way bullets in a single rapid session. Upon death, it spawns 2 Eternal Guts and 1 Eternal Clotty.

Notes

• From the Afterbirth DLC for Rebirth, Mama Guts has a chance to spawn 1 or both Scarred Guts upon death.

Trivia

• From the original game, they can be found in Necropolis. They no longer appear in this chapter from Rebirth, however.
