Pinkie Pie is Evolutionlicious!

Revival Herb, because it gives -15/20 to friendship while fully reviving Pokémon, having the strongest drop (minus trading which resets). Why primary Normal-type? Normal-type is a gimmick, unspecialized "default" type, many Normal-type Pokémon learn various elemental moves. Also, Puddinghead's evo is something aka Burmy/Wormadam... Oh, and if anyone ask WHY the Gala Pie is the only evo to still be able to change forms? Well, it's still normal Pinkie Pie, but stronger, unlike other evo.
