Will Smith in 7lbs had a jellyfish in a tube...
And that may not be a sea creature... but I don't find it all that tasty looking.
Especially the 'dirt' part of the name, makes me think you just took a bunch of Oreo's, crumbled them all, put them in a bucket of sand and started stirring.
I bet it's real tasty when you taste it though... I hope...
