Ah I see what you mean there. I'm really not how to respond to the story of your username, I was just going with the idea of the Pikachu clone of the Marshiso region being a regional variant from Scanania the reason why I chose finland is that you said you were one working on your own pokemon at one point, and yeah I do becuse I have done quite a bit of research and devilment.
I apologize for the late reply, it taking me a while to come up with Pokédex entries for my region's fakémon I have already come up with. also I been playing a fair amount of Pokémon Legends Arceus mostly for research into the crafting mechanic.
As for the Psyduck line is found in a lot of Reginal Pokédexs so it was a no brainer in adding to the Marshiso Regional Pokédex Also its Regional evolution's name comes from Thorium and Duck and the general idea that its a kappa hence it's fondness of cucumbers.
Marshiso Region's Creation Story
Long ago Great Rabbit Jackanitou batlled the Dark Spirit Plaguendigo, it's said that during their battle their powers combined formed an egg that hatched into Intinca (the Sun), Mama Killa (The Moon) and Gaiatlas (Turtle Island) born also were the Four Sacred Directions which are Shakok The White Lynx of the North the guardian spirit of Winter, Morityema the Blue Bird of the East the guardian spirit of Spring, Miochin The red Salamander of the South the guardian spirit of Summer and Shruisthia The Black Bear of the West the guardian spirit of autumn. Each of the Four Sacred Directions contributes a vital part of wholeness of the Marshiso region not only do they control the seasons but the elements as well their Earth and water became the original form of Meracocha. their Fire and air became the original form of Yuchama. However when Yuchama rebelled it was cased to the Earth and lost its wings, which were granted to Meracocha by the Elipsoluna stone. the war between Meracocha and Yuchama formed the fine grates lakes born out of them arose five serpentine Lake Guardians. It was around 3,000 the Planet of Meyru was destroyed by the ultimate weapon and the rains of which became known as the Dragon's Eye into the left flank of Mount Meru, very few of its native Pokémon survived. also long ago as Turtle Island was rising Geysourex was created to not only maintain the Geothermal activity of the geysers and hotsprings in the Marshiso region but also create the Oceanic Preserve. Jackanitou created Cerespelt to teach mankind how to farm and look after the land and Kodaikai to teach them how to mine for metal ores and how to use them to create technology.

Please keep in mind that the names of the guardian spirits are placeholders until I can think of better names for them.
Welcome to the world of Pokémon my name is Charles J. Appleseed I'm just a Super Nerd at the moment, I'm currently researching the Dragon Force which is the form that the infantry energy took within the Marshiso region, I along with my team are researching how the dragon Force have changed the Pokémon within the Mashiso region. You see a while ago I received a Falinks from my friend Mikael (insert favorite tree here) and though it the move Collaborate oddly it evolved into a new Pokémon I call Squadragoon. there are many new Pokémon yet to discover here with in the Marshiso region, perhaps I'll investigate the rumors of there being Zombie Marshmallows within the graveyard soon, until my next research post cheerio my good fella!
