A bit of help, if I may; On Mom's foot fight's floor, there is a deformed, different looking skull somewhere outside of the boss room. Blowing it up gives you a "Fool" card, allowing you to teleport out of the boss room and go to the Beast path. Hope this helps!
Did you know… Blue baby gets cheaper devil deals! instead of all 3 soul heart costs, they’re only one or two cost. (He also has the special ability to get a fly from every poop he destroys) Also, did you know that every character has a “damage multiplier” Judas has a very high one, meaning that +1 damage from something like pentagram is actually +1.35dmg due to a 1.35x multiplayer!
