Measure
A tsunami will pick up a bunch of shellfish and dump them on your shore, so you take a knife and measure them.
You can't eat shellfish that are too small, so you place your knife along them to measure them. If they're big enough, you stick the knife in and eat them raw.

None
All of the shellfish you measure that are too small go into your sock (そく). Once the sock is full, you swing it around your head and lob it back into the ocean.
If you measure one of these shellfish and it's too small, stuff it right into your sock. Then once the sock measures about 12 shellfish long, toss it back to sea!
