Once I took my dragon on a walk

Once I took my dragon on a walk.
We went around the entire block.
We came upon a harpy, who's talons went clack-clack.
My dragon chose to eat her, as a little snack.
We turned left at the corner, and there we met a mourner.
So saddened by the visit of a banshee.
My dragon spat a bit of flame, and made the banshee accept the blame.
We continued down the road, and met a very ugly toad.
My dragon gave it just one look.
That was all it took.
The toad hasn't been seen since.
And neither has the prince.
Our walk ended by the lake, when my dragon complained of a bellyache.
After much hacking, the harpy emerged clacking.
And my dragon and I watched her fly away.
