I made another set because the first one I did sucked and I put no effort into it, but then again, it's not like this is any better. I put at least more time into it.
Special Info: Can only evolve under certain seasons.
Sammakko: The Frog/Turtle Pokemon. It's a water type. It spends most of its time underwater. Whenever it comes out, it can expel the water through a blowhole in its shell.
Skurnako: Sammakko usually evolves into Skurnako during the summer. Sammakko spends most of its summer in the water do to the hot weather. It collects so much water and doesn't come out so another blowhole is created due to all the pressure causing it to evolve somehow.
Postrako: The Ice/Flying type. Skurnako's water freezes whenever it tries to pump it out during the winter. The ice punctures its shell causing the top layer to break. Postrako just uses the broken shell as armor during the cold weather. It learns to control the ice on its back and eventually can use it to fly, but not that fast or high.
