I’ve been nasty since my birth

When it comes to nasty dragons

I’m the nastiest on earth

I have a nasty, nasty temper

And my breath is nasty too

I was nasty to my parents and I’ll be nastier to you

It’s my nature to be nasty

Nasty, nasty night and day

I will act completely nasty

If you’re in my nasty way

Yet I largely pass unnoticed

As I nastily go by

I’m a nasty, nasty dragon

Just a nasty half inch high
