Sleestaks were awesome! For some reason, for a young kid in the seventies, they were a little scary. They didn't speak, they moved really slowly, but the had a certain je ne sais quoi. Something that was just a little creepy. I think it was just the raspy wheeze they produced and the inhuman way they moved. Okay, so I'm not getting it across. Yeah well, I'd like to see you trapped in prehistoric times surrounded by dozens of those slow moving raspy humanoid lizard folk! Let's see what you'd think then, huh!
I think, here, in this picture, they are conducting an orchestra or something. SCARY!
