I'm stupid with puffy paint... any help?

I was puffy painting a poncho for my spanish class and long story short, I was stupid and neon pink puffy paint got smeared on my red cloth Coach.... Unfortunately I did not notice until the next morning so it was nice and hardened. :( My mother will kill me if she finds out.

I've been picking at it with my fingernails all day, which has helped, and I read some crazy stuff with vinegar and Goo-Gone, but I'm kind of nervous as that could further ruin the bag...

Any ideas to get it off? It's not really soaked in too much but is more of a very thin smear about a centemeter wide on the side of my bag.

I would love any help with the matter...

Thanks!
