Perna...yes, that exact episode. It encouraged me because Beaver had Henry trained to where he would come when she called for him..haha, I wonder if it's possible? The things I take in while watching Noggin with my toddlers..haha. Anyway, yes, I enjoy them. My neighbor claims they are both females..but they're a bit young to actually determine yet. How can you tell then apart anyway?? All I care is they are the same sex. I'm going to let the kids come to the store with me and pick out a ball and some tubes for Mister and Tinkle Bits..it'll be their presents to give out this year. It is so fun having them.
