Do snails make a noise when eating?

by the way the answer is not no!

I live in an area amazingly overrun with imported brown snails (imported for food use, BTW) I keep a strictly organic garden so I hand pick snails. Iusually find between 50 and 100 every time I go out to pick them this time ofyear. They do indeed make a sqeaking noise when they are picked up. This is the sound made as they retreat into their shells and air is forced our through tiny spaces

funny ey rach!
