Watch Those Low Ceilings When You Swing

Watching a coworker try to cut up a partially submerged tree while standing in chest deep water, I found myself wondering if they've ever done Texas Chainsaw Massacre underwater? "20,000 Bloody Leagues Under the Sea", or something like that.
Somebody must have at some point. It makes it so much easier to explain why the hapless victims don't simply flee the lumbering killer when they're trapped within a confined space. Space ship, undersea facility, boat with a distinct lack of lifeboats, it comes out to the same thing. I suppose an explanation for why there's a chainsaw in an undersea facility might be required, but it can't be that difficult. There's a greenhouse, it has sentimental value, it was sealed in the watertight comparment of some boat full of logs that conveniently sank near where the facility would be built some decades later.
