A perky little Pea crab
knocked on an oyster’s door
He bellowed out for food please
then hollered out some more

The sleepy slimy oyster
didn’t really have a say
as the cunning little Pea crab
barged in to live that day

That cute and crafty Pea crab
shelter, air, and food all free
sponged of his oyster roommate
gently rocking in the sea
