Extra Cute Snail Alert! When I got my new houseplants home from Concord, I found this guest clinging to them. I put him on my spider plant and gave him some cilantro, but he refused it and clammed up. Now he’s hiding inside his shell, all shut down tight to stay moist. Does anyone know if this is the type of snail that grows up to be the big mucous brutes that slime around out back and eat everything?
