Me and my friend are working on a new fantasy story together, and we wanted to come up with our own version of classic Fantasy races like Dwarves, Elves, Goblins, Orcs, etc...
I like to add a twist to them that makes them very different than you expect them be; But also I feel like in a lot of recent fantasy stories people have taken some of the "Fantastic" out of fantasy. I know it's the "classic" look but, too often Elves and Dwarves are literally just like Humans with something a little different about them and are rigidly type casted into one or a couple of specific Stereotypes:

Dwarves are almost always short muscular hyper masculine men with big thick beards, wearing Viking inspired helmets, and talk with a scottish accent. They are gruff, speak very bluntly and might be super literal or can't take a joke; They are very industrious crafters and builders, said to be some of the best in the world but also very strictly traditional as to never make too much progress out of the realm of medieval fantasy. They Love Booze-Hate Elves, like to Boast about how strong they are, are obsessed with gold and other treasures, live in Gigantic cavernous mountain halls, and greatly favor Axes and Hammers over all over Weapons.

These Dwarves on the other hand are like nothing you would find in the natural world. I wanted them to exhibit some of the classic Dwarven traits you expect like having big beards, being skilled craftsmen, and living underground, but I also wanted them to truly feel like a magical creature.

Dungeon World Dwarves are like a weird cross between an Ant and a Potato-man. Dwarves have a Queen who's larger than all other Dwarves and doesn't even look human. She produces all other Dwarves from her body as buds, then once they are big enough, attendant workers will sever the buds from the queen and bury them to finish growing in special nursery garden chambers which help adapt the developing bud to whichever working role they are meant to serve in the colony.
After they fully develop they just pop out of the ground as a conscious Dwarf who know exactly what their role is, and immediately get to work. When they first emerge from the ground, Dwarves have legs but no arms. Over time they will grow their own arms with tools specific to their jobs and can grow arms which also double as tools for their specific job, but when they start out they may borrow an arm from one of the older worker dwarves who can just pop off their own arms off if they don't need it, and stick it to another dwarf, they may even have an entire group of dwarves who's job is to grow and farm spare arms for new dwarves so there are constantly extra arms in circulation, but even with a borrowed arm Dwarves seem to prefer to grow their own.
One arm is typically smaller and more human-like, meant for more versatile general usage, while the other arm tend to be exceptionally large and even weirdly proportioned having multiple joints or branching arms, which are coated in an Earth-like or Metallic Exoskeletal shell that grows into the shape of tools. These Tools are highly durable, and resist extreme heats, and while attached to the dwarf that grew them, if they sustain damage from use, they are capable of regenerating. They can also make several arms at a time if necessary, but they always seem to specifically have an odd number of arms and are never entirely symmetrical. These arms are also not fixed in one place on the body, they are mobile and able to slide around all over the dwarf's body.
