Here it is:
Starts with Al whipping out a kitty and Ed telling him "No, they can't keep it." Al resorts to glomping his brother to convice him. Ed, fed up, does his hand clap-thingie and turns Al's armor into a cat form. Ed laughs and Al bites him. The End.
Yeah, it was a rush job but I'm happy with it. I don't expect an award or anything but tell me what you guys think. I'm kinda hoping to turn it into a comic.
