"Do piers have special spawning mechanics?"

#PokemonGO: Since the Halloween event is on it's easy to notice areas that have different spawn mechanics to usual, including:NestsElectric biomes: Voltorb and MagnemiteWater biomes: Magikarp, Psyduck and DratiniI believe that water biomes have other spawns depending on location:River: SlowpokeCoastal: Tentacool, Seel, Shellder and LaprasOn top of this, piers seem to have unusually high amounts of non-halloween spawns. It almost seems like the spawn table is huge (including electric pokemon etc).Has anyone done any research on this? What have you experienced? Lapras are pretty rare in Melbourne, you can only find them at piers (but maybe these are the only spots people check near the ocean frequently). via /r/TheSilphRoad http://ift.tt/2enPP6U
