>In HeartGold and SoulSilver's game data, Nosepass can learn Head Smash via breeding, but no Pokémon that can learn it are in Nosepass's Egg Group, Mineral, making it impossible to pass down the move legitimately. This learnset data was then removed in Generation V. The move remains unavailable to Nosepass in Generation VII, despite the fact that Aegislash and Sudowoodo would now be able to pass down the move.
