To get a pokemon with 3 1 hit ko moves, you need patience and luck. This is the instructions. 1st breed female mudkip(alll pokemon stated include any evolutions) with male rhyhorn that knows horndrill (he learns it level 38) make sure baby has horndrill and is male. Breed this with a spheal. make sure that the spheal learns horndrill from mudkip2 and learns fissure from the egg(this is random). Get it to level 49 without evolving to learn sheer cold. And there you go, a spheal with horn drill, fissure and sheer cold.
