This mod is set in the world of the Mario games, but in which these games, and Mario himself, are simply legends.

This is a significant mod that adds enough new content to the game that it can be played fine without any Vanilla creatures, entities, or plants, however it does not change any of the game's base files. If you want to play a Mushroom World-only game, delete the raw/objects folder and then place the downloaded raw files in their place. If you want to play crossover Dwarf World and Mushroom World, simply place the new files in alongside the old. All of the new objects are uniquely named, so it should play well with any other mods you choose to throw into the mix as well, provided that they don't change the base files either.

There are three playable races in this mod. To see which one you are playing as, on the embark screen, press tab until you find a list of neighboring races. The one at the top is your civ's race. To switch civs, press tab until you find a list of civ names and then pick the one you want. (Toads usually name their civs after domestic objects or peaceful concepts, Koopas prefer names related to fortresses or protection, and Shyguys tend to have names related to freedom or wildness.)

Current features include:

Three fully playable races, each with their own unique fortress-building style. Cook special powerups and collect Power Stars as the domestic Toads, build a strong army complete with monsters and magicians as the militant Koopas, or open up portals to sub-space and let your creative juices flow without limit as the wild, surreal Shy Guys.

Lots of new races to trade or fight with in Fortress Mode: Beanish, Bumpties, Bub-ulbs, Bob-ombs, Frog People, Mole People, Doogans, and many more...

Over 15 unique races to choose from in Adventure Mode, each with their own special abilities and stats. Soak in the sunlight as a mighty Pianta, stick to the shadows as a sneaky Squeek, wield magic powers as a wandering Shaman, or take the extra challenge and try to survive as a Goomba.

Tons of creatures ranging from the well-known to the obscure, many with some very unique properties. Every biome has a different set, making each game a new experience.

Plenty of new secrets to find: Attack enemies with the Firebrand or Thunderhand techniques, turn them into harmless objects as a Wizard, become a giant, and others...

Lots of power-up vegetation. Eat Super Mushrooms to grow into a giant, or Fire Flowers to throw fireballs for a limited time, Super Leaves to transform into a flying Tanooki, and tons of stat-boosting foods.
