Princess "Oom" OomLout is a supporting character in Planet Sheen.
"Princess Oomlout, is the Emperor's daughter. She also has two faces, an extra one popped out when she sneezed too hard. After that there was a new holiday and a song of Oomlout's popping out day. One face is a bubbly cheerleader; the other is an intense seductress. To Princess Oomlout's dismay, neither of them has any power over Sheen. She is deliriously in love with him and shows it by licking him to hard. This is very exciting to the Emperor, who can't wait to see the couple marry. Sheen, on the other hand, is terrified."
Princess Oomlout has purple skin. She wears a yellow dress and has no hair except for her ponytail of dirty blonde hair. One of her faces has small, girly eyes and pretty eyelashes. The other face has a huge buck teeth and bulging eyes. She has two toes on each foot. She has wings on her back.
Princess Oomlout is one giant body and two frightening faces: one is bouncy, bubbly and ditzy like a cheerleader; the other is slightly more hideous and really intense. Oomlout is deliriously in love with Sheen and shows it by giving raffenhoffers (licking) and whirlyhoffers (a whirlpool of ranffenhoffers) him with her super long tongue. Sheen hates this more than anything and can't stand her at all, but the Emperor thinks they’re in love, which means Sheen cannot stop her affections, yet will do anything to avoid them and her at all costs.
- In concept art, Oomlout was blue.
- In the original premise of Planet Sheen, due to the Emperor being evil and ruled planet Zeenu with an iron fist, it is unknown if Princess Oom was part of the original premise.
- The voices of the two faces of Oom is voiced by Candi Milo in her normal face and Debi Derryberry in her ugly face.
