Snails, What's The Point?

This is the most pointless creature on this planet! I've watched it for an hour now and it's gone nowhere. It's eye's are on the end of sticks for some reason, which is obviously of no use because even the most spastic of birds seem to be able to catch and eat it before it's "sticky eyes" have seen it coming. As for it's shell, well, you might as well tell a teenager that his powers can't hurt you because of the bin liner you have sellotaped to your chest. Then watch his face light up as he rams a carving knife into your heart, as seems to be the trend at the moment.
Stupid twatty mollusc.
