So I just gave it the text of my homebrew hodmedod race to chew on, and asked it to make a race based thereon. I've had to edit it a bit, change a fe3 details, but I could almost just drop this into my campaign handbook. If you have something really good to feed it, it regurgitates something better than it otherwise would.
Hoppit
by Cab DavidsonHoppits are small, rabbit-like humanoids. They stand at around 3’ tall with long ears and fluffy tails. They have short, soft fur covering their bodies and come in a variety of colors, ranging from white to brown to black.
Character Class and Experience: Hoppits are known for their nimbleness and quick reflexes, making them natural thieves and rogues. However, in principle they can pursue any character class, although there are no known hoppit magic users or merchants. Hoppits require the same experience per level of experience as humans.
Hit Dice: Hoppits use the next lower dice than is standard for the class they pursue. For example, a hoppit fighter rills 1d6 for HP, a hoppit cleric rolls 1d4.
Languages: Hoppits have their own language of chirps and hops, but they can also speak common, elven, and halfling.
Combat, Armour and Weapons: Hoppits are not skilled in heavy combat, and thus cannot wear armour but can, class permitting, use a shield. They can only wield small weapons. They have a natural armor class of 8, which may be further modified with dexterity, magic items, etc.
Due to their quick reflexes, any creature not immune to normal weapons engaging a Hoppit in melee combat using a weapon shorter than a spear must make a saving throw vs. Paralysis each round or be struck by the Hoppit's swift kicks, dealing 1d4 damage.
Senses and Movement: Hoppits have excellent hearing and can detect even the slightest of sounds. They have a movement speed of 150’, making them incredibly fast and agile. Hoppits can burrow through earth at a rate of 5’ per turn.
Hoppits have a natural ability to jump and leap and can jump up to three times their height in a single bound. This allows them to easily navigate through difficult terrain and escape danger.
Due to their small size and furry nature, Hoppits are resistant to cold temperatures and can withstand harsh weather conditions without issue. However, they are vulnerable to fire and take double damage from fire-based attacks.
