Happy - a poem by my best friend

I love my music, It's happy, and it makes me happy.
Happy, happy, happy.
I like happy.
I also like giving gifts.
That makes me happy, too.
My friends aren't always happy though.
They think I'm scary.
I'm not scary,
....Am I?
Uh oh,
where'd the music go?
I think the man forgot again.
Maybe he'll wind it soon and i'll be happy again.
It's been too long.
Where'd it go?
I'm getting madder and madder now.
I want my happy music back.
I'm not happy anymore.
I'm mad.
Very, very mad.
If he's not going to wind it, I'll MAKE him wind it.
I have red gooey stuff on my hands now, but thats okay,
because my happy music is playing again and the bad man
stopped moving.

Can you guess who this is?
