They ought to make in-betweening an approved form of "enhanced interrogation". I bet it's cheaper than waterboarding.
Anyway, how do you make a snail intimidating? Imagine this sort of Gigantic Snail in the mountains, and it's got fire on its back. Sure that fire looks hot, and sure the thing makes mountains look like your backyard anthill, but any immediate sense of intimidation is mitigated by "when was the last time you were outrun by a snail".
These are people I see around the school. I know some of them, but others I don't. I hope no one recognizes themselves or anything. That'd be pretty awkward, no?
