Got kicked out, Last Loud on Earth?
This article contains information about an episode banned in Poland, Russia, Turkey, Indonesia, Malaysia and Finland[note 1] due to the presence of Clyde's fathers for the former five, and prominent horror/zombie themes for the latter, and therefore will be unavailable to any user from these localities, with the exception of this specific article.

"Last Loud on Earth" is the twenty-first episode of the fourth season, the one-hundred-seventieth episode of The Loud House.


After a night of zombie movies, Lincoln and Clyde find an empty Loud house and assume it's a zombie apocalypse.


Lincoln and Clyde are hanging out at the Loud House, watching the Swarm of the Zombies movie marathon. Just when Lincoln and Clyde prepare to watch the remaining four movies in the series, Lynn Sr. tells the boys that they need to head to bed. Upon entering Lincoln's room, Lincoln reveals that he knew that they'd be sent to bed at this moment, and says that he plans to watch the marathon in Lisa's underground underground bunker. After pulling out the inflatable exit slide, Lincoln and Clyde proceed to watch the remaining movies, which takes the entire night.

What's that in the distance?

Once the fifth movie ends, Lincoln and Clyde quickly exit the bunker and enter the house. To their discovery, the interior of the house is in ruins, everyone is missing and the power is out. After searching around some more, the boys discover that every house is in the same condition: the interiors are in ruins and everyone is missing. Lincoln assumes that they woke up in a zombie apocalypse, but when Clyde comments that it's not an apocalypse unless there's a zombie, they suddenly spot a silhouetted figure approaching, causing the boys to believe that they are in a zombie apocalypse, and run away into a hiding spot. Seeing the dangerous situation they're in, Lincoln suggests that they head to their secret hideout.

While trying to avoid being caught, they approach the Burpin' Burger for a bathroom break. While doing so, they suddenly hear noises and realize that there's another zombie present. They quickly slow it down by dumping garbage on it while they escape through the window. Heading to Flip's Food & Fuel, they attempt to stock up on supplies, but they hear Flip from the office, but discover it's actually just a recorded voice on a walkie-talkie. At that moment, they hear a noise and discover a zombie lurking in the store. The boys manage to stop it by dumping nacho cheese on it. At Tall Timber's Park, Lincoln and Clyde enter their secret hideout and turn on the radio in hopes to find contact. On the radio, Mayor Davis tells the listeners that if they are still outside, everyone is congregating at the Royal Woods Mall. Realizing that they're not the only survivors, Lincoln and Clyde proceed to head to the mall.

After exiting their hideout, Lincoln and Clyde attempt to head to the mall, but have to fight the zombies on the way. The boys manage to completely get them out of the way by tricking them to go in a dumpster and rolling it away. As they approach the mall, the dumpster suddenly hits a roundabout, causing it to head towards the boys. Fearing that they doomed their parents, Lincoln and Clyde proceed to fight back by using water guns filled with juice, and when they run out, the proceed to fight them with hand-to-hand combat.

The "zombies" were actually the boys' dads all along.

Suddenly, Rita tells the boys to stop, saying that they're beating their fathers. After a closer look, it turns out that the zombies were Lynn Sr., Harold and Howard all along. They explain with raspy voices that last night, Mayor Davis warned of a terrible storm approaching and urged all Royal Woods citizens to hang out at the mall for safety. While the sisters, Rita and Lynn Sr. got the message, Lynn Sr. states that he and the McBrides will try to find the boys while Rita takes the girls to the mall. With the truth revealed, Lincoln and Clyde explain that they were in Lisa's bunker at the time, and Rita initially intends to punish them for sneaking out like that, but believes that the suffering they went through today is punishment enough (much to Lynn Sr.'s dismay, since he and the McBrides suffered numerous injuries due to Lincoln and Clyde attacking them). Lincoln and Clyde apologize for the mix-up and for hurting them at all the locations they went, like the Burpin' Burger, Flip's, Tall Timber's Park etc. However, the dads remark that none of them went to Burpin' Burger. This causes everyone to believe that there really was a zombie lurking.

At the Burpin' Burger, it turns out the "zombie" at the restaurant was actually Flip, who was using the town-wide panic/storm commotion to his advantage by getting free food.


Lily, Katherine Mulligan and Seymour have no lines in the episode.

Physical distribution

This episode is available on the "Bienvenue chez les Loud: Saison 4: Partie 1" DVD.


  • Lincoln and Clyde using Colonel Austin's methods of fighting zombies is similar to Lincoln using Rip Hardcore's methods of survival in "Mall of Duty" and "Washed Up".
  • This episode, along with "Tails of Woe", aired on the same day of Chris Savino's firing since 2017.
  • The access code to Lisa's underground bunker is revealed to be her birthday, and this is something Mayor Davis, Mr. Grouse and the entire Loud and McBride families know.
  • This episode reveals that Lincoln and Clyde have a secret cave hideout at Tall Timbers Park, and Lincoln comments that they have had it for at least 5 years.
  • Howard has brown hair instead of his usual red hair in the episode. He was previously seen with brown hair from "11 Louds a Leapin''" and "Snow Way Down".
  • The clothes Flip was wearing looks similar to Hector's.
  • The plot of the episode is very similar to "The Price of Admission". These episodes involve Lincoln watching a film he's not allowed to, which leads to him getting into a traumatizing misadventure. In the end, he admits he messed up to his parents and Rita says that his crime is already a punishment enough for him.
  • Irony:
    • Lisa, a child genius, isn't that great at making secret passcodes.
    • Flip made a warning call against stealing his store, but he himself steals from the Burpin' Burger.
    • Lucy gets frightened by a zombie despite being a nightmare fetishist.
  • Foreshadowing:
    • The scenes where the zombies in the movie fight were used by Lincoln and Clyde to survive their encounters with the "zombies".
    • While Lincoln and Clyde fight the "zombies" with hand-to-hand combat, the fathers' bodies can barely be seen through the silhouettes.
    • Flip wasn't among the citizens at the mall, indicating that he was the "zombie" at Burpin' Burger.
      • Other pieces of evidence that support this was that his silhouette did not match those of the fathers, and that the noises he made while at the Burpin' Burger sounded different than those made by the fathers.


  • Last Loud on Earth - The title of this episode is a reference to the popular post-apocalyptic comedy TV series The Last Man on Earth.
  • Each of the Swarm of the Zombies movie titles reference an iconic movie or known expression:
  • Daphne & Velma - The premise of this episode is similar to this film, as they both involve a duo thinking their dad(s) is a supernatural creature.
  • Batman (1966) - When the boys attack their dads, the action words popping up call back to this television series.


  • Plot hole: It was shown that the storm had cut out all electricity to the house, so it is unknown how the electricity was still running in the underground bunker for Lincoln and Clyde to watch their movie marathon.
  • When the boys land outside the Burpin' Burger bathroom, Lincoln isn't seen wearing a belt. But at the construction site, he is.
  • After Lincoln and Clyde find everyone, some of their positions change after the dads explained everything:
    • Lori and Leni switched sides.
    • Lori was the one holding Lily, but then it's Rita.
    • Luan is standing where Lucy was, Lucy is standing where Lynn was, and Lynn is standing where Luan was.
    • Lana and Lola switched sides.
    • Lisa was standing on the left side of the twins, but then switched to the right.
    • Katherine Mulligan and Seymour disappeared after the dads explained everything.
      • Rita, Luna, Mayor Davis, and Mr. Grouse are the only characters who stayed in the same positions.
  • Possible: When the Louds and McBrides were telling Lisa that her passcode is her birthday, Mr. Grouse and Mayor Davis also replied.
