Can't find AAMFP secret door files

[gruzz]

(Nearly) all Machine for Pigs entities work fine as long as you move the entity's files into your custom story folder. c:

I did end up finding the secret wall passages, but not the bathtub one. Don't think I'll need that one anyway.

How did you!? I want!! I actually love the stuff from AAMFP, they look really nice.. The walls and the floor, really want!
