A dinosaur for christmas

A dinosaur for Christmas
is the only thing I need.
It doesn't matter if it's slow
or one that's built for speed.
A massive one, a tiny one
or one that's in between.
A dinosaur that's muddy brown
or bright and shiny green.
I don't care if it's big and tall
or really old and ugly.
I don't care if it's rough and tough
or soft and cute and snuggly.
A spiny one will do the trick.
A scaly one is fine.
As long as it's a living, breathing dinosaur,
and mine.
I promise if you bring me one
I'll never ask for more,
That's all I want for Christmas:
just one single dinosaur.
