Gravel Grind

The platypus does not have teeth,
And feeds on worms, shellfish and snails
Found on the river bottom 'neath.
So what about chewing details?
Well, this is where pouches do aid,
A pouch in each platypus cheek.
Each trip to river bottom made,
Gravel the platypus does seek,
And scoops some up with the food too.
Back at the surface the food stash
Stored in the cheeks, but how to chew?
Well, the gravel therein does mash.

Gravel is a great blender for
Easing of the swallowing chore.
