A Thousand Feet & a Foot-Long [Common Meter]

The millipede was a foot long,
but, some might ask, whose foot?
Its own feet being quite petite
might suggest Lilliput.

But though it wasn't a footlong foot,
it was long for a bug,
a worm, a beetle, a wood mouse,
a spider, or a slug.

A snake that long would be a babe,
or, at least, quite stunted.
So, now I find my amazement
being a bit blunted.
