Neopia is a virtual planet with fantasy lands inhabited by Neopets and other virtual creatures. Each land has a different theme, such as pirates or prehistoric times, and their own shops, games, and attractions.[5] Neopia follows its own calendar and time zone, which runs concurrent with real-world Pacific Time,[6] and has tie-ins with certain real world holidays such as Halloween and Christmas. It has its own economy and stock market based on Neopoints. Users can earn Neopoints through various means including playing games and selling items, which can be invested or used to buy various virtual goods and services.[7] While there is no set objective for users, interactive storylines are sometimes released that introduce changes to the planet such as new lands.
