Most longtime residents whom have been around for over a decade remember the "Greenies" sim. The place was only two rooms, but was built at such a huge scale that normal-sized avatars looked mouselike in comparison, with small green aliens around the place in whimsical situations. Sadly in 2010, the sim was closed. Recently, there was a location that gave residents a similar experience, Oxygen owned by Justice Vought at the River sim. Gemma Cleanslate recently went there, and had a look around.
