Psst, come over here...

 Be gentle how you place your steps,
Be quiet with your heavy breaths.
Something to show you, I have got,
It cost me little but means a lot.
A few years gone, I forget the year,
I was given a pond by my ol' dear.
Not very big, but big enough
Not very posh, in fact rather rough.
Down I dug with my garden spade
huffing and puffing, sweating in shade.
At last, it was done, filled with rainwater,
planted some stuff, just like you oughta.
Dreaming, I saw it filled with pond fae
whose lustrous green skin did shimmy to dry.
Year by year passed, nothing appeared.
Was nothing coming? Nothing, I feared.
Then this month I saw, as I sat by the side,
a quick little move as something did hide.
Held in my breath, pushed aside the dog,
leaned right over and there was a FROG.
A little brown chubby, a frog nonetheless,
I'd not been more shocked had it worn a dress.
So, quietly come near, be careful if you can
for I want you to see my amphibian.

Note
My Pond fae shouldn't be confused with Plumatella repens
