Cute love him. I have to tell you though, that I thought Oscar was an entry in the Childhood Hero Challenge. When I was about 3, my mom tells me that Oscar was my hero, and everything grouchy was what I wanted.
Not the best choice probably, but we all survived.
Anyway, he is the cuddliest, cutest grouch I've seen and you can make him as grouchy as you want telling him that I think that.
