Pandora

Pandora is a stereoscopic 3-D planet. Leela notes that the planet is extremely dangerous, and she is unable to see properly while on the planet as she only has one eye and no 3-D glasses.

Production
The planet is a refence to the moon with the same name featured in the 2009 science-fiction film  by James Cameron. The fact that the planet is 3D is a reference to the film being produced in 3D, and relaunching the popularity of 3D films.

The planet is very similar to the Avatar moon, with many floating islands with forestation on their surface. A major difference, however, is that the planet is in, with the entire planet divided into red and cyan hues that produce a 3-D image when seen correctly, and it is not a moon, but a planet.
