You see some of them moving aside, clearing a path. That scraps the
theory about movement too slow to be noticed; you can notice these
moving just fine. Then, from the direction in which the path is being
cleared, you hear a slow, repetitive sucking noise. It comes closer
and closer as time goes on. You would jump back out the way you came,
but it is too high for you to reach. You see a great shape looming out
of the darkness. An outline slowly becomes visible.... That of a giant
snail.
You totally freak out. "What do you want??" you scream
histerically.
The monstrous snail responds. Its voice has an awful rasping quality
to it; snails are not the creatures best equipped for speech.
"Wee waant... Yoouu..."
You back up to the wall, wanting to run away from the creature, but
blocked by the solid rug of snails on the floor, which you absolutely
refuse to touch, even with your shoes. You shriek, "Why? Why is
it you want me?!?"
The snail replies, "Wee neeed yoouu
beecaauusee..."
You get up and look around you. The slugs and snails everywhere are
DISGUSTING!!! You back up against the wall, as far away from them as
you can get. They all seem to be standing still... Or perhaps they are
just too slow for you to notice their movement. They ARE snails, after
all. You have an odd feeling that they are watching you, however.
