While the big, noodly, stretched-out humans look horrifying when they're still in the holes, just try to think about what they'll be like when they get out. Big, floopy things that can't walk, so they just fall flat on their face and twitch around.
Unless they actually can walk. In that case, it's absolutely horrifying.
The holes were even shaped to accommodate people's hair!
Kinda reminds you of those old cartoons where a character would fall off a cliff and make a hole in their shape (hair included).
"Si-sir! It's slowly coming this way!"
This somewhat brings to mind the scientists kind of awkwardly standing around, checking their watches and eating sandwiches, before this horribly noodly man-thing plops out the end and twitches on the ground.
