I want them to stay furry! BUT, it is really funny to imagine what they might be like as human kids.
Bamf would be about five, I think. Just going into Kindergarten. He would have dark hair and huge blue eyes, and be very, very inquisitive. He would always ask questions, like "Why is the sky blue? What are you doing with daddy? Will you tell me a story? When can we eat? What kind of car is that? Can I play? Can I have a cookie?" And he would interrupt everything you are doing to ask a question. He would also be "starving" all the time, and enjoy playing video games with daddy. He would not be afraid of trying anything or asking about anything. He would like learning new things.
Pixel would be younger, 3 or 4 (even though they are only a few days apart in age), and always getting into trouble. She'd have light brown hair that would be curly and blue eyes, and she would make messes all the time. She would spill the blocks, break the dishes, steal cookies and cover her face in chocolate, and climb into your lap while you were watching a movie and fall asleep there with her head flopped back, curled up in a funny position with smudges on her face. She would make mud pies and eat bugs and run and run and run! And she would laugh all the time, and be afraid of monsters under the bed. She would love trying new things without learning anything about them first.
