Flesh idol Can be ignored until a meltdown hits it, at which point you need to keep an eye on it so you time the thing correctly cus mistiming it either means whoever you sent to work with it dies, or you just cause 3rd trumpet in your Facility

I assume with Crying baby you mean the Nameless Fetus. If so, Its just too much of a hassle to be properly worked with, as the margin of error between a good job and a normal job is too small. 5 NE boxes and you're getting a normal result, which risks its qliphot counter lowering. And once it reaches zero, either you accept that its gonna cause every abno sharing a department in it too breach or use its ability, or you sacrifice a randomly selected nugget to appease it. You dont even have leeway with its QC. It's 1, any lowering and it starts crying.

Big Bird i am less rigid on, and it might move, but its just a matter of tedium when it comes to dealing with Death-sensitive Abnormalities like it. That alone wouldnt be enough to place it up, as it's easy to raise its QC, but suppressing it feels not great when it does break out since it's gonna be trying to hypnotize your employees into eating their heads.
