First, you have to capture a *male* Smeargle, and a *female* Pikachu. Make sure that the only attack Smeargle knows is Sketch (preferably more than one). Breed them together, and you'll have a Pichu, that hopefully knows Sketch. Evolve it into Pikachu, and then battle a friend w/ the Pikachu in your line-up. Make sure your friend has a Pokemon that knows Surf. Battle the Pikachu and the Pokemon w/ Surf. Get your friend to use Surf on Pikachu. (Make sure Pikachu's strong enough not to faint!) Then use Sketch. Voila! You now have a Surfin' Pikachu! If you want, you can trade it to someone's Pokemon Yellow and then play the Surfin' Pikachu Game at Fuschia!
