''Moogles hate having their pompoms ruffled (don't we all?), but the pompom rufflers just keep coming in droves. Maybe that's why the moogles use holograms to run their shops now, while they kick back at home.''

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 Accessory Shop in the First District, the Synthesis Workshop which is run by some of the Moogles is opened and Sora can 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 (or even enemies) 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 358/2 Days
In Kingdom Hearts 358/2 Days, Moogles appear in Organization XIII coats. Like the other games, they help with item synthesis, but it is currently unknown how this will work. It is also unknown wether they hold any alligence to the Organization or not.

Kingdom Hearts II
In Kingdom Hearts II, the Moogles now use holograms to run their synthesis shops, except for Mog in Radiant Garden and Elmina in Twilight Town. 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. There is also a special Gummi ship modeled after a Moogle.

Origin
Moogles are small creatures and a race that originally spawned from the Final Fantasy Series. The Japanese name is a portmanteau of the Japanese words mogura (mole) and kōmori (bat). They have appeared in all Final Fantasy 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".
