Who lived up in a tree.
He was a two-toed tree toad
But a three-toed toad was she.

The three-toed she-toad's heart,
For the two-toed tree toad loved the ground
That the three-toed tree toad trod.

From her tree toad bower
With her three-toed power
The she-toad vetoed him.

It is really not quite right
To light night-lights with their slight lights
On a light night like tonight.
