Oh Crap

Upon picking up 3 items from the following list, Isaac will heal half of a red heart each time a pile of poop is destroyed.

E Coli	5.100.236	Turdy touch	Enemies that touch Isaac are changed into poop.	1
Dirty Mind	5.100.576	Filthy friends	Destroying poop spawns friendly Dips that follow Isaac and damage enemies. Destroying different types of poop spawns different Dips with special effects.	2
Montezuma's Revenge	5.100.680	Oh no...	While firing, Isaac charges up a short-ranged Brimstone-like diarrhea beam that shoots behind him.	3

Repentance only:

Butt Bombs	5.100.209	Toxic blast +5 bombs	+5 bombs. Bombs now cloud up the screen, briefly damaging and confusing all enemies.	2
Skatole	5.100.9	Fly love	Flies become harmless or less dangerous depending on the type.	0
No. 2	5.100.378	Uh oh...	Continuously firing tears for three seconds causes Isaac to drop a Butt Bomb, which damages and confuses all enemies in the room when it explodes.	2
Hallowed Ground	5.100.543	Portable sanctuary	Spawns a white poop familiar, which turns into a white poop when Isaac is hurt. White poop has an aura that halves tear delay and can block enemy shots.	1

Despite being poop-themed, Skatole, Butt Bombs, and No. 2 do not count towards the transformation.
Poop created with Flush! and E Coli do not heal Isaac when he has this transformation.
Oh Crap! is useless for ???, as he cannot utilize red hearts in any way.
The Scat Man challenge starts with this transformation.
