Assuming Standard Gravity

Slugs have feet
But slug has foot,
Around which sometimes
Fringe is put.
They’re mostly mantle,
Tail, and slime,
Plus tentacles,
And what’s sublime
Is, when you slice
A slug you’ve found,
1/32^nd weighs a pound!
For which fact we’ve
Bored Brits to thank.
The things we learn
When weather’s dank!
