Rescue Worker?

Riddle me this, Batman -I know worms come up during the rain, because the ground gets soaked and they'd drown or something...but HOW do they get to the middle of the street, or, the middle of my GARAGE??? There's got to be some kind of magic involved. I have to admit, while it kinda skeeves me out, I try to return the little buggers to the relative safety of the rorrest floor, versus the paved street. Slugs, on the other hand, are on their own.
