Felucia was a planet filled with giant frickin' mushrooms and other enormous fungi, not to mention semi-translucent creatures of equally-ridiculous sizes. Mario and Luigi spent a lot of time there, doing things that defy imagination. Felucia sucked because hot alien females kept getting killed there, like Aayla Secura (killed by clone trooper wankers), Barriss Offee (clone wankers in an AT-TE), and Shaak Ti (killed by the Secret Apprentice). Do not ever let Mission Vao, Guri, or Jaina Solo visit Felucia, because frankly, that world's reputation speaks for itself.
Felucia was where the Smurfs grew up. Originally they were born on Pandora, but because they were too vertically challenged they got put in a cardboard box and sent to Felucia, where they were illegal immigrants.
