Lost Song of The Oompa Loompas

During renovations of the vast Wonka factory, old recordings were found in the former Oompa Loompa dormitory. These tapes contain songs like the one below that have never been heard by non-Oompa ears. It is sung to the same tune as all the other Oompa Loompa songs.

Oompa, Loompa, doom-pa-dee doo
Why are we orange, what are we to do?
Oompa, Loompa, doom-pa-dah dee
Once we were not as you now see.

Why are we here to work in this - muck?
Which smells like it's from a garbage - truck!
Why do we make this for people to eat?
Don't they know that it's - not - a - treat?

Not to us,
Not to us,
Not to us,
Not to us,
Not to Oompa Loompas!

Oompa, Loompa, doopity dight
Now our skin is orange and tight,
Plus our eyebrows have turned white.
That's the Oompa Loompa's plight.

Didn't Willy know that we might react,
to this goop that smells like a yak?
We make it into bars and other snacks.
While new growths come out - on - our - backs. (something like a camel)

Oompa, Loompa,
Don't get in a snit,
Because we're allergic to chocolate.
We'll keep making it just for you
'Cause that's what Oompa Loompas loompadees Do!
