Nidoking was always a pretty cool looking pokemon, though I never used him in a game until I played FireRed last year. This Nidoking here is grumpy because he has been left with the kids. There is also a mischievous Pikachu that has taken advantage of the Nidoking's colorblindness and snuck its way into the family. You can see the process recording over at My Livestream Channel
Aww, I loved Nidoking and Nidoqueen in Pokemon Yellow. Pikachu was useless with defeating Brock so I always got a Nidoran male and evolved it into Nidorino to double kick Brock's rock Pokemon to death! It would be awesome to see a pick with Nidoqueen and King with their babies.
