I know, I had that same problem. Like I went to throw it at my friend (I threw it pretty hard, too) and it didn't do anything, so I picked it up and threw it at the ground softly and it pops. xD -,-;
I managed to get her a funny card, but not a present yet. I'm thinking about some kind of lotion or something. And if not that, then I'll just give her one of my old toys/plushies that I don't play with anymore. x3
