AHHhhh you are both perfect. o3o I want to cosplay Ice King and I've thought it kinda an impossible task almost.. but seeing your Ice King has really given me inspiration! ^^ Best Ice King I've seen, too!
It was from a site that sold prosthetics for Halloween. I can't remember the site name, I thought it was mostlydead.com but I'm not seeing the same exact nose. They do have other noses however. I remember this one was called 'witch nose.' Look at prosthetics costume sites, use words like 'latex nose' and 'witch nose' in your searches. I also found this: [link] It's a set but it comes with a pointed nose. Good luck!
