Yo guys what's a mystery dungeon I have no money for it.

Pokemon Mystery Dungeon is a franchise with exclusively the creatures themselves. It's a dungeon crawler, with the protagonist being once a human.

However, in lore, such phenomenons are rare, and often occur when a major threat is on the horizon. Though in some cases some just appear lmao

I think I played the demo, you are a human who wakes up somewhere, then another Pokemon helps you and you sleep in a hut?

Just simplifying it of what I know.

Within the DX demo, yeah. However, we don't have to limit ourselves to in-game lore, there are entire civilizations you can create using the core of Mystery Dungeon.

Pretty much, lol

Throughout the game you explore randomly-generated dungeons, fight in turn-based battles, and try to reach a certain floor! The games are plot-based though, so there’s a lot of fun dialogue and interactions as well

^^ and yep, I’ve seen some pretty extensive worlds made with the concepts of PMD!

Is Rowlet a choice? Its my favorite Pokemon by far.

The only limit is merely a suggestion to discourage legendary Pokemon as an OC. Otherwise, go crazy! You don't even need to follow the base design, you quite literally can do anything with your Pokemon. An RP community I'm in for PMD has some of the most gorgeous designs out there that branch away from the exact Pokemon.

dang

Doesn’t have to be an official one—I do a rp with someone on their message wall, for example

I believe that is referring to those hosted on the threads, but not too sure.
