Backstory

I was a half-blood Griffindor student in the 3rd Year. But a couple weeks before Mid-term... Tragedy struck! :
I was in Hogsmeade enjoying a butter beer when I entered a unusual shop... It had many potion ingredients I have never heard of and I was sure no other student has heard of either. I wanted to ask Professor Snape about them (yes I am that old), but it was his first year as a teacher in Hogwarts, and being the stubborn student I was, I told no one about it. I bought everything (nearly) the potion ingredients shop had that was magical and left grinning stupidly, I decided to make my own potion and little did I know how dangerous that was...Especially without telling anyone.
The next day I went to the girls bathroom where Moaning Myrtle was and asked her to shut up while I entered the stall next to her and started brewing a potion with everything... Veela Eyelashes, Hippogriff beak pieces... etc
After putting in all of the ingredients I waited smiling like an idiot... Suddenly... I died. I don't know how and if you ask anyone they would say: Um no one knows how The Grinning Belle died... (yes that's the nickname given to me by the students, and no it's not my real name...). And they named me that because I died grinning. And whenever I just relax I start grinning... It's really annoying! And since I was a Griffindor I was supposed to be the Griffindor ghost... But Nick died before me. And I was left just being the less known Griffindor house ghost, me and Nick are the only Griffindor house ghosts... No one knows about me! Except some older students... But whatever! Thank you for learning a bit more about me.

When I was alive (and dead too!):
Patronus: Hippogriff
Boggart: Potion full of those pesky ingredients and it's flying with angel wings but it's wearing devil horns
Wand: Holly with dragon heartstring 13" and hard flexibility
