So, what are Moogles??

モーグリ, Mōguri, originally Romanized in Japan as "Moglie"

Mōguri, the Japanese transliteration of "moogle", is a portmanteau of the words mogura (土竜, mogura, mole) and kōmori (蝙蝠, kōmori, bat). This is fitting as moogles tend to have small eyes and red/purple wings.

Moogles are small fictional creatures that appear throughout the Final Fantasy, Mana (Seiken Densetsu) and Kingdom Hearts game series.

They first appeared in Final Fantasy III.

Good-natured creatures, moogles are usually white or tan, and their most notable feature is a white antenna protruding from the head with a small red or yellow ball at the end. They have small red or purple wings, and their ears are shaped like those of a cat or rabbit. They have developed through their many game appearances and have many different forms today.

They tend to say "kupo" (クポー, kupō when they talk (it is actually a sound they make), more commonly to finish a sentence. For example, "What a beautiful day, kupo!".

Moogles, along with chocobos, are considered the mascots of the Final Fantasy series.

It should be noted that a Moogle's favorite food is the Kupo Nut, which is rumored to be the reason that Moogles use "Kupo" in their dialect.

Many names of Moogles have the prefix Mog- or Ku-, an example of this would be in Final Fantasy VI and Final Fantasy IX where every Moogle had a name.

Moogles are frequently featured as creatures that may be summoned by the Summoner or Caller class of playable characters. Typically, moogles are lower-level summon spells acquired earlier in a given game. For example, Lulu uses a Mog doll as her attack in FFX.

Mog is also often used as a stand-in word for moogle, even when moogle is the term used to describe the species in that particular game. Incidentally, Final Fantasy VI, Final Fantasy IX, and Final Fantasy Crystal Chronicles each had a moogle whose given name was Mog.
