Genetically modified lice
Look like humans and aren’t very nice
....Having grown person-sized
....They now hunt, so disguised
It’s not something you’d want to see twice

A Judas Breed, perhaps?

A doctor adapted some chums
By stitching their gobs to their bums
So the front could eat stew
That would then trickle through...
(See to what end recycling comes!)

Hmm, I might have given the last one away by having included it in my poem in Non-Met -- or did you already know it Annie? Have you seen Human Centipede? I hadn't heard of it until I read an interview with one of the actresses a couple of weeks back. I was kind of tempted ...

He wakes up in a hospital bed.
Is he dreaming – or perhaps he is dead?
Cut to London at dawn,
Looking empty, forlorn
Is this Day of the Triffids? I said.

No, I haven't seen all of Human Centipede. I stumbled on it by accident and sought out a couple of You Tube clips. The idea fascinated me. I haven't seen Mimic either, but looked it up (and found out about the Judas Breed).
Your latest one, though, has me bewildered. I shall light my pipe and play my violin. That usually works.

Mimic was a pretty bad film as I remember. The Human Centipede does sound like it could be worth a watch though.

Yes, the last one was pretty obscure in terms of clues. Maybe I can come up with a better version. Meanwhile, here's something else, albeit a similar genre:

With the zombie infected ascending
A lone scientist’s will is unbending
It’s a war, will he win it?
Yes, of course, but last minute.
Read the book for a far better ending.

Did Amen Corner appear in it...?

Whoops - cross-posted. I was asking about #124.

Now I'll refill my pipe and consider the zombies of #126.

"Bend me, shape me, anyway you want me"? Sounds like a contender for the Human Centipede soundtrack! But no Amen Corner connection that I know of to the last two.

This was what I was wondering about for the hospital awakening:

Some parallels with the Human Caterpillar, it looks like, at least on the non-elective surgery front.

Here's an attempt to give a much bigger clue on the hospital awakening one, though you'll have to seen it to get the whole thing, I think:

For one lunar month he is out
When he wakes up there’s no one about
Cut to London at dawn
Looking empty, forlorn.
That's from from Day of the Triffids! we shout.
