The Moai (モアイ, Moai?) is a recurring Easter egg in the Final Fantasy series, appearing in unexpected locations, usually on World Maps far from important locations, and having little to no function whatsoever. In most cases, they are a reference to the moai, monolithic human statues from the Chilean island of Rapa Nui (Isla de Pascua).
A stone appears on the Red Moon. This one is an allusion to the infamous face on Mars myth rather than the moai. A "happy face" crater and rock formation, inspired by the Galle crater of Mars, also appears.
In the DS Remake, if the player stole Dark Matter from Zeromus and uses it on the Stone Face, they will fight Proto-Babil.
A moai appears at the bottom of the ocean. It serves no other purpose than being an Easter Egg.
In the Game Boy Advance version, it is revealed that the moai is in fact a structure constructed by the Ancients, used to transport people from the "Real" world to that of the Sealed Temple, and disguised to look like a relic from some long-lost civilization. The device was sealed off however, and only became accessible due to the recent earthquakes.
In PuPu's sidequest, the UFO? enemy is sometimes seen abducting a stone face with its light beam. Additionally, colored stone faces are involved in the Obel Lake sidequest, though no graphics are shown for these.
At the outset of the adventure, the Prima Vista crashes into the Evil Forest and Zidane is left to make a big decision. After recruiting the help of Steiner and Vivi, Zidane and company travel into the dark depths of the forest to save Princess Garnet. Hanging left at the first fork will take the player to a serene waterfall glowing in the evening Mist. On the right side of the background is a tall moai, looming as high as the locale's alpine treeline. This zone is unique; aside from a trivial command prompt and the Easter egg, it is an itemless dead-end that holds no practical purpose in the game whatsoever.
At The Gapra Whitewood, at the "Maintenance Exit" past the save point, in the background one can see what resembles a moai face on one of the buildings in the north. Afterwards a scene reveals this is a building in Palumpolum.
One of the player icons is a moai from Final Fantasy V.
