Biggs and Wedge, inspired by two Star Wars characters of the same name, appear in numerous games as minor characters, sometimes as comic relief. The later games in the series feature several males with effeminate characteristics. Recurring creatures include Chocobos and Moogles. Chocobos are large, often flightless birds that appear in several installments as a means of long-distance travel for characters. Moogles, on the other hand, are white, stout creatures resembling teddy bears with wings and a single antenna. They serve different capacities in games including mail delivery, weaponsmiths, party members, and saving the game. Chocobo and Moogle appearances are often accompanied by specific musical themes that have been arranged differently for separate games. Final Fantasy is also well known for its enemy monsters and creatures.
The series' popularity has resulted in its appearance and reference in numerous facets of popular culture like anime, TV series, and webcomics. Music from the series has permeated into different areas of culture. Final Fantasy IV's "Theme of Love" was integrated into the curriculum of Japanese school children and has been performed live by orchestras and metal bands. In 2003, Uematsu co-founded The Black Mages, a instrumental rock group independent of Square that has released albums of arranged Final Fantasy tunes. Bronze medalists Alison Bartosik and Anna Kozlova performed their synchronized swimming routine at the 2004 Summer Olympics to music from Final Fantasy VIII. Many of the soundtracks have also been released for sale. Numerous companion books, which normally provide in-depth game information, have been published. In Japan, they are published by Square and are called Ultimania books.
