The house lost a snail

Hey, guys! As a child I didn't know how this snail is placed in your house). As the snail is twisted and drawn into the sink. Ha ha ha. Yes, I biology know not very thoroughly)). When I was little and found an empty snail house , I thought the snail went looking for a bigger sink, which became cramped in the old house. And it turns out that the clam is growing along with their house.
This cabin is empty.
