The third incarnation of the My Little Pony line began in 2003, and is generally referred to Generation 3 (G3). Hasbro released only Earth ponies from 2003-2005. They released Pegasus ponies in 2005, and Unicorn ponies in 2006. The ponies live in Ponyville which is centered around Celebration Castle. Many of the original ponies have since been re-released in different poses or outfits.
Most ponies in the line have shiny or pearly bodies and matte symbols resembling tattoos on one side, now referred to as "Cutie Marks".
Other limited edition ponies have been the Pony Project promotional ponies and Rosey Posey, who was given to attendees at a charity dinner held by Hasbro.
Recognizing the adult fans of its line, Hasbro has released special collector ponies that are noticeably different from the regular G3. These ponies are available usually through special channels such as the annual My Little Pony Convention and the San Diego Comic Con.
