I saw that this character has parry, a drone, and is a robot. I NEED THEM. I saw them lying around on the final floor, but didn't have anything for them. Do i take the oil from the second floor to fix it? I saw that it said something about a head and arm, but can't find them.

I found how to get the leg (click see more to find out how), but I reached the body again after attaching the leg and then dying to the final boss, AND THE LEG WAS GONE

Leg is found by bomb boosting over the gap at the end of the second level (need explosive weapon), then blasting a hole in the wall after jumping over the gap, and then there is a robot that you can rip the leg off of.

There are books in the library that give hints on where to find both parts. You need to bring both in the same run, which means you have to do part of it melee only.

Just to add to this ***warning M.O.K.O's head spoilers*** you have to beat Magnolia and go back to the starting room and shoot at the middle of the ceiling (the middle of the pit you fell from) then once you "kill it" the head will drop and so will a flare gun - ( a nod to the buddy using it to get help but also an explosive weapon to get the leg in the second floor) these wont drop until after you beat Magnolia but if you use an explosive weapon to boost your self into the ceiling you can take damage. (for whatever that's worth)  

lil more info if your thinking about using the random guns every room curse from the devil girl (every room you get 2 random weapons and that includes the robot parts) they don't work when you try it just says " you try to jam the part on but you realize its just paper Mache" so don't waste your time.

both of the parts can be found on your own by reading the M.O.K.O logs 1 and 2 the hint is after the MISFIRE: part.
