I always was impressed by the size of it's doors. I wonder what controls them?

You share that in common with Abe.

Which one is which?

This is where a certain amount of opinion comes into it. I personally think that the ghost with one leg is the Scrab-guy, the spirit with one arm is the Paramite-dude, and the weirdo with no waist is the Meech-geezer.

Makes sense, since Scrabs are famous for their spikes, Paramites for their face fingers and, to a lesser degree, Meeches for their spike-things. I also find it quite symbolic, since Paramites and Scrabs were at the time, dying out, and so each representative has lost a limb, but Meeches were extinct, and so their representative had lost a lot more of his 'body'.

I am interested to learn about the Mudoncho Temple.

I'd wager that guess any day. But let me just say this is one piece of information that I'd like to keep for The Oddworld Encyclopedia, if that's acceptable.
