I went through all the trouble to breed a Hippowdon with good IVs and the egg move Slack Off because the Pokedex page says Hippowdon learns Ice Fang/ThunderFang/Fire Fang in Gen VI. It didn't learn the moves upon evolution, like I thought it would. Upon some research, I learned that you can teach it these moves with a Move Tutor in Gen IV. Is there a way it can learn these moves without me having to backtrack two generations?
