Western Animation / Planet Sheen

Earth's ambassador to Zeenu. Be very afraid.

Spin off of The Adventures of Jimmy Neutron, and the 29th Nicktoon overall.

One day, Jimmy Neutron's intellectually-challenged friend Sheen Estevez sneaks into the secret lab and boards Jimmy's latest experimental rocket.

Before too long, he finds himself accidentally stranded on the planet Zeenu, four million and one lightyears away from home. There, he becomes an ambassador to the local purple-skinned Zeenuians, the Emperor of whom believes him to be a hyper-intelligent being sent from the heavens to guide them. He makes some new friends too, including Doppy—an alien who looks remarkably like his old friend Carl—and Nesmith—a highly intelligent astronaut chimp who tries to fix the rocket so he and Sheen can return home to Earth.

Unfortunately, a man named Dorkus Aurelius, whose house Sheen accidentally wrecked during his crash-landing, is bent on destroying him.

Premiered alongside T.U.F.F. Puppy on Nickelodeon October 2, 2010, the series was met with lackluster reception. About half of the first season was aired on Nickelodeon before they moved new episodes to be broadcast on Nicktoons only, similarly to Back at the Barnyard (which was produced by the same company). The last episode to be aired of the first season was released on February 15, 2013, with no likely followup, resulting in no resolution to Sheen's return to Earth.

No connection to Charlie Sheen, or whatever planet he's from. note 

This series contains examples of the following tropes:

  • Abhorrent Admirer: Princess Oom towards Sheen.
  • A Day in the Limelight: You only get 1 guess on how this is to Sheen.
  • Aerith and Bob: Oom, Dorkus, Nesmith, and Bobb.
  • Aliens Speaking English: Lampshaded.
    Sheen: Wow, Zeenuian sounds just like English! (Slowly turning to look at screen) What an incredible coincidence!
  • Apes in Space: Nesmith.
  • A Planet Named Zok: Zeenu.
  • Art Evolution: The animation software used is a much bigger improvement than The Adventures of Jimmy Neutron, is the same software as used in Back at the Barnyard, and it shows.
  • Betty and Veronica: The hideous Oom is Betty and Aseefa is the Veronica.
  • Big Bad: Dorkus Aurelius
  • Big Good: The Emperor, although only to some extent. While he may appear generous and kindhearted at first, especially towards Sheen, deep down he's just a big dumb child with zero knowledge as to how to run a planet who seems to have little to no interest in the well-being of his subjects, frequently inventing ridiculous events and regulations just to tame his own boredom.
  • Brain Bleach: The episode ''The Oomlick Maneuver" has the wonderful line.
    Sheen: I have seen things so horrible they will never ever go away, no matter how much I think of soap.
  • The Cameo: In the first episode, after convincing himself that it's all a dream, Sheen imagines waking up on a farm - with Otis and Pig walking by the window.
  • Cloud Cuckoo Land: Zeenu.
  • Courtroom Episode: "Trial By Jerry."
  • Deadpan Snarker: Nesmith has his moments.
  • Disappeared Dad: Dorkus.
    • Not only is he not seen, Dorkus does not even mention him
      • This is highly speculated that his father is either dead, was a deadbeat father who left his mother, or had done something to make his son disregard his existence.
  • Disguised in Drag: In "Joust Friends," Sheen attempts to get out of a duel. Doppy is the only one who's fooled.
  • The Dragon: Pinter, to Dorkus.
  • Everything's Better with Monkeys: Mr. Nesmith the chimpanzee.
  • Evil Chancellor: Dorkus, although partly subverted. Yes, he is mean and evil and never above cheating if it serves his interests but his only goal seems to be winning back the Emperor's favor, in order to do which he needs to get rid of Sheen. Even if he does consider his ruler to be incedibly vain (and seeing as he's totally right about that), he never once tries to actually depose him.
  • Expy:
    • Doppy who is Carl's Expy appeared in the pre-premiere commercials, and at the ending of the first episode, prompting Sheen to stare in Jaw Dropped awe.
    • Mr. Nesmith seems more like Jimmy Neutron's counterpart of the show.
    • Dorkus and Pinter are this to King Gooboot and Ooblar.
  • Fluffy the Terrible: The warrior who can kill in over 107 ways, including emotionally...Bobb.
  • Full-Name Basis: In the pilot, Sheen calls Jimmy Neutron by his first and last name just to illustrate how dumb he is for not realising what the initials on the sticky notes stand for.
  • Blue Skinned Space Babe: Aseefa.
  • Gasshole: Aseefa becomes this after losing her roove in "Feeling Roovy".
  • Huge Schoolgirl: Princess Oom.
  • Idiot Hero: Guess who.
    • Doppy also goes under this category, but is mostly Sheen's sidekick.
  • Interspecies Romance: Sheen and Aseefa.
  • Meaningful Name: Planet Zeenu's name sure does sound like "Xeno"
    • Also, Dorkus Aurelius, who wants to become Emperor, is named after Marcus Aurelius.
      • It should be noted that Dorkus has shown zero desire to take over Zeenu as Emperor; it should also be noted that his only desire is for Sheen to be gone by any means necessary. Despite similarities, he is not Jafar.
  • Missing Mom: Dorkus and Princess Oom.
    • Dorkus' mother is only mentioned and never appears in the show.
      • In the episode "Boy Next Dorkus"
    Pinter: Alright, *picks a conversation starter card* if you were to go back in any time in history, when would it be?
    Dorkus: Easy. My own birth to applaud my mother.
    • In the episode "Thanksgetting"
    Dorkus: I hate that as a child I never got the Cloaked Avenger Action Figure with Magic Fire Breath, because my mother was all, *makes his voice higher pitched* "No! You'll burn down the house! Nyehnyehnyehnyehnyehnyeh..." It's all I ever asked for...

    later in the same episode

    Pinter: Ah, you see good things can happen to you when you open your heart.
    Dorkus: Ooh...I wonder if it has the Magic Fire Breath my mother thought was "Oh so dangerous!" *he points the action figure towards his house and activates the "magic fire breath" causing his house to burn up and collapse* Oh Grock!
    Pinter: Oh, it works...
    • In the episode "Act I Sheen I"
    Dorkus: *walks out of his hiding place towards the group consisting of Sheen, Aseefa, the Emperor, Nesmith, and Doppy* Hello all.
    Nesmith: *gasps* Where did you come from?
    Dorkus: My mother...
    • Princess Oom's mother, the Empress, never makes an appearance until the episode "Nightmare Sheenario" which is also the last episode she will be shown in.
      • According to Doppy, she comes out once every 365 days in order to retain her beautiful appearance.
  • My Nayme Is:
    • D-O-P-P-tralalalalalalalalalala-Y. The tralalalalalas are silent, but felt.
    • Bobb. Two Bs just aren't enough.
  • Never My Fault: Mr. Nesmith tends to receive this treatment from Sheen.
  • Only Sane Man: Nesmith and sometimes Dorkus.
  • Potty Emergency: Sheen has one in the first episode after a long ride in a space ship.
    • A whole episode is devoted to this. Tea anyone?
  • Put on a Bus: In an inversion, the whole supporting cast of The Adventures of Jimmy Neutron.
  • Rubber-Forehead Aliens
  • Running Gag:
    • Sheen's Uncle Miguel gets mentioned (and a picture of him is shown) quite frequently.
    • Dorkus's house getting destroyed.
      • Only in the episodes where Dorkus appears and only when he is near his home.
  • Series Continuity Error: When Sheen first meets Doppy, it was very briefly at the end of the pilot, and Sheen clearly knew his resemblance to Carl. Then, come the very next episode and Doppy's proper introduction, Sheen does not catch his resemblance to Carl at all, not even after flashing back to all the good times they had together.
  • Ship Sinking: Hey, remember Libby? Sheen doesn't seem to.
  • Shout-Out: Mr. Nesmith, the chimpanzee, complete with trademark pompom hat.
    • A one-off villain is named Bohrok the Destroyer.
  • Spin-Off: Of The Adventures of Jimmy Neutron.
  • Split Personality: Princess Oom with her two faces.
  • Talking Animal: Nesmith the Chimpanzee.
  • That Was Objectionable: A few times in "Trial By Jerry".
  • Unfortunate Names: The series' villain, Dorkus.
  • Unknown Rival: It never gets to Sheen's thick head that Dorkus wants him dead. The others are pretty clueless as well.
  • Visual Pun:
    • Carl wears glasses, thus making him a “four-eyes.” His Expy in this series actually has four eyes, complete with similar glasses. Behold the eight-eyed slug man.
    • The planet, as seen during the intro, looks like the typical screwball design.
