So after a few weeks, I've noticed that Growlithes have started spawning somewhat regularly, which is great!
But over the past few weeks, I've noticed that they only spawn in a specific place (a park), and only after dark. It makes sense, being a "dog" Pokemon, and being a dark type.
Additionally, other evidence of this is water type Pokemon - Krabby, Squirtle, Horsea, Magikarp - all have been spawning more regularly near water.
Is there anything about times and locations to do with Pokemon spawning? Is there any kinds of lists to show what Pokemon spawn where, and when?
