Okay, so maybe I shouldn't be coming up with ideas this late at night. I have much happier death sequences during the day when I haven't been thinking about story lines for the twins all day.

Apologies in advance. Probably not for young eyes.

First thing's first, we gotta do a little prep work. First we drug him and start getting a lot of bone softener in him. It won't kill him,
but it will keep him in one place. His bones will stop holding their shape, his muscles will not have the structure in order to function properly and his organs will start to crush themselves. This will give us a lovely Blake blob. Something nice, compact, and probably easily bent out of shape. Put the Blake blob into the bottom of a very small, six foot deep hole. Maybe deeper.

Next, we have acid. Something nice and flesh eating. Pour this on. It will corrode him in a delightfully, turning him into a bubbling Blake blob. Quickly following the acid wash, preferably while the acid is still feasting, apply liberal amounts of hot asphalt. Fill hole to the top. Cool asphalt to solid. Voila, a buried bubbling Blake blob.

Even if he does manage to reform under all that and get the space to straighten his limbs out how they're supposed to, he'll still be stuck at the bottom of an asphalt pit.

...

Or you could vacuum seal his head in a plastic bag. He still needs air right?

Ah, forget it. I'm going to sleep.
