I loved K9, after living with a 70kg great dane who sleeps with his smelly but on a chair and his head on the floor people would appreciate a robot dog, I have threatened to replace King with a K9 model when he is naughty. For starters, robot dogs don't fart.
I loved K9 for the same silly reasons I loved the cardboard spaceships and rubber monsters and stuff hanging on strings... because I just do lol.
