There was a baby dragon, Norberta was her name,
She used to live with Hagrid, from Harry Potter fame.
Owning such a dragon, was quite against the rules,
So Hagrid had to give her up to other hapless fools.
She quickly showed ferocity to anyone she may,
But she was still so little they just sent her on her way.
She found her way to Windsor Park and found a plastic cave,
The coordinates are to that place for anyone so brave!
She kept a little golden horde she measured day by day,
But all too soon outgrew her cave and had to fly away.
If you desire to seek her stash, come find this priceless hide,
But keep watch for Norberta... her return might leave you FRIED!
