How can I make this cartoon character nose for my Halloween costume?

I'm dressing up as Lois Griffin from Family guy. If you've never seen it: http://l.yimg.com/img.tv.yahoo.com/tv/us/img/site/46/71/0000034671_20061021010507.jpg
I have everything for the costume, but I want to make my nose look like hers somehow. How might I make it and attach it to my face? What do you think?
