Moogles are a race originally from the Final Fantasy Series. They have appeared in most games since Final Fantasy III. They are known for their white fur, purple bat-like wings, red pom-poms on their heads, and end many of their sentences with "kupo".

Many "Final Fantasies"

Kingdom Hearts: Chain of Memories
A strange race that seems to pop up just about anywhere.

In Castle Oblivion, the moogles run shops where Sora can trade in unwanted cards.

Kingdom Hearts II
"They appear in about every world. Are capable of using rare items to make extremely powerful armor, weapons, and other things. May seem small but are useful."

Kingdom Hearts
In Kingdom Hearts, they can be seen in Traverse Town after the destruction of their respective home worlds.Later on in the game when Sora uses the green trinity mark in the Accesory Shop in the First Distict,the Synthesis Workshop which is run by some of the moogles is opened and Sora an then go there to allow the Moogles there to use some of his items to make new ones.

Kingdom Hearts: Chain of Memories
In Kingdom Hearts: Chain of Memories, moogles appear in "Moogle Rooms"; a special room generated by a map card of the same name. Inside, Sora is able to cash in his unwanted cards for "moogle points" and is able to spend accumulated moogle points on purchasing new card packs. You can also obtain moogle points by collecting the red orbs that sometimes appear when you strike things with your Keyblade. The first time you speak to a moogle in a new room you will receive a free card packet consisting of five different attack cards.

Kingdom Hearts II
In Kingdom Hearts II, the moogles now use holograms to run their synthesis shops, except for one moogle in Radiant Garden, Mog and another in Twilight Town, Elmina (according to Jiminy's Journal, it is because they hate getting their pom-poms ruffled). They are all named after famous Final Fantasy moogles, such as Stiltzkin and Artemicion.

Kingdom Hearts 358/2 Days
In Kingdom Hearts 358/2 Days, moogles appear in Organization XIII coats. Like the other games, they will help with item synthesis, but it is unknown how this will work currently.
