soft frogs

I alluded to this this once, briefly in a poem.
It is worth mentioning again, in detail.
The sofest thing I ever held in my hands
was a live frog. A plain green everyday Ohio frog.
I was helping him out of danger, taking him back to the pond.

It really surprised me.
No struggle, nor fight.
The sensation was neither wet, nor sticky.No claws or edges.  Not cold. Just soft.
Like  holding water in a thin membrane.
