What do you guys think of these wild Pokemon for Route 8?
The "South" area is the area with regular weather, i.e. sun like most everywhere else. It would include the Land. The "Middle" area is rainy and the sea is more choppy, and the "North" area is cold, the waters rife with icebergs and chunks of ice, and snow falls from the sky.
The Sunken Ship would be near this area, but the wild Pokemon doesn't include what would be found in the ship. I think that should be done separately.
The Icetope is an encounter that can randomly happen when smashing floating chunks of ice that block the way, like when Geodude randomly appears when smashing rocks on land. The white Lavoon is for the Captain Isaac/hunting the white whale sidequest.
