Cousin stuck in seabed

Give me your cockle!

Oh, your foot expands to 4 times the size of your shell? My husband's little foot can barely kick off the seabed to avoid predators. Why don't you let him watch you drill me? He gets off on being a cuckle. Do you want to drill him a little, too? He's a bi-valve.

You can also find moon shells with those same holes bored into them.
