Way back in 2009, I got a 20-second video clip, released by Kowalski Brothers. May have been uploaded to UMD... I can't remember.
In it, Mouse is featured and she's got "Red Nose Day" on her mind. Naked and dripping in food-slime, she produces a red clown nose from somewhere and has a quick giggle. What a cutie!
I don't know whether or not K.B. would be happy with me (re)sharing their video clip, but here are a few stills to give you an idea. Enjoy!
