Using only Diamond, Pearl, Platinum, HeartGold and SoulSilver, what is the maximum number of ribbons a single Pokémon can legitimately attain?
Don't include Pokémon traded from other games (e.g. Emerald or any Pokémon spinoff games other than the ones listed), event-only ribbons, or ribbons that cannot legitimately appear together on the same Pokémon without cheating.
Don't include the one ribbon that appears on some event Pokémon; but: for a bonus point, do any event Pokémon come with more than one ribbon?
