craftgrrl | Costume with a mohawk? And Gizmo ears for doggies.

I have short hair and I want to integrate a fauxhawk into my costume.
I thought about a rocker or Goth Barbie, but I'm afraid those ideas are way overdone... what do you guys think?

Also, I want to dress up my dog like Gizmo from Gremlins. He's a brown and white Aussie/Sheltie mix, so his hair is perfect for it, but I want something that indicates a costume, so I figured a pair of Gizmo ears would be the best route.... I'm not sure. I don't want to just put a tag on him that says "Gizmo." That's too goofy. I've done a google search for Gizmo ears and found nothing.

Suggestions are needed and appreciated.
