Episode number: 63b
Timmy helps Mark celebrate FLARG, a Yugopotamian holiday, only to find out the holiday involves destroying the host planet.
Tropes:
- Accent Uponthe Wrong Syllable: Mark repeatedly points out that his "appendix" will blow up if he doesn't celebrate a proper FLARG. Cosmo of all people lampshades this at one point.
- Answer Cut: At the end of the episode, Timmy asks Mark what world he fired his missile at. It then cuts to Fairy World, burnt to a cinder.
- Artistic License – Military: At the end of the episode, Mark states that his appendix is no longer a Defcon 5 threat. DEFCON 5 is actually the lowest level, meaning peacetime conditions. DEFCON 1 is the highest level, signifying nuclear war.
- Blatant Lies: The second day of FLARG, L, stands for "Lie", and Mark makes up all sorts of lies to Timmy, which ends up in him getting rejected by Trixie.
- Fartillery: The first day of FLARG, F, stands for "Fart". Mark lets out an enormous fart that kills several birds and disgusts Timmy and his fairies.
- Foreshadowing: Early on in the episode, Mark explains that the Yugopotamians always go to another planet to celebrate FLARG, never holding the holiday on their own planet (duh!). This is because the last day of FLARG requires the host planet to be destroyed.Mark: Why do you think we never hold FLARG on Yugopotamia?
- Fun with Acronyms: Each letter in FLARG stands for a different form of celebration each day. In order, they are Flatulance, Lying, Amnesia, Rhanksgiving, and Goodbye.
- I Regret Nothing: Just before blasting himself and Wanda off to escape Earth exploding, Cosmo says this to Timmy. At the end of the episode, after pinning Fairly World getting blown up on Binky, he says it again while blasting himself and Wanda off in another pod.
- Kidanova: Timmy somehow managed to befriend a grown woman named Carly.
- Laser-Guided Amnesia: The third day of FLARG, A, stands for "Amnesia". Timmy thinks they're about to have a great party, only to be reminded that the party already happened, and Timmy doesn't remember anything. Though, pictures from it show that the party had Chip Skylark performing, Timmy had fun with his friends and got to impress Trixie, Crocker and Vicky got arrested, and Timmy somehow got a tattoo with the name "Carly".
- Loophole Abuse: The last day of FLARG has the host planet destroyed; the home planet cannot be destroyed. Since Earth is Mark's home planet now because of him hiding from Mandie, he works around it by destroying a different world.
- My Significance Sense Is Tingling: After Mark wallops Chester in the face with a kickball just after he had gotten his braces off, Dr. Bender is elated that he senses a coming influx to his wallet.
- Non Fatal Explosion: Fairy World when the FLARG rocket bombs it.
- Noodle Incident: Whatever Timmy did to befriend Carly and both of them getting tattoos of each other's names remains a mystery.
- No-Sell: Cosmo and Wanda cannot interfere with the FLARG preparations because Timmy wished it were authentic.
- Reduced to Dust: Jorgen does this to Binky when Cosmo pins the destruction of Fairy World on him.
- Sadistic Choice: The final day of FLARG puts Timmy and Mark in one. It is revealed the last day is destroying the host planet that FLARG was held on, with one of the rules specifically being "Don't destroy the home planet". Timmy realizes this means Mark can't destroy Earth either since it is his home now, which Mark agrees with. However, if he doesn't destroy the world with his missile, his appendix will for not completing FLARG. They manage to work around this by having Mark find another planet to use his missile on, which is successful.
- Screw This, I'm Outta Here: When Mark's missile is about to destroy the Earth and they can't stop it, Cosmo shoves Wanda and himself into an Escape Pod to Fairy World. At the end of the episode, he does it again when Jorgen demands to know who was responsible for Fairy World being blown up.
- Simple Solution Won't Work: After watching the FLARG celebration and noting how Mark is depressed to be missing it, Timmy asks why he doesn't just go home for the holidays. The celebration broadcast then shows that Mark's jilted fiance Mandie is still waiting (violently) for him to return.
- Take a Third Option: On the last day of FLARG Timmy and Mark need to either let Mark destroy Earth with his missile to complete FLARG, or if they don't due to it now being Mark's new home, then his appendix will destroy the world anyway for not finishing FLARG. Timmy suggests that he just find another planet to destroy so the condition is satisfied, any planet. Mark redirects the missile to Fairy World, which ends FLARG and spares Earth.
- The Scapegoat: Cosmo pins the blame on Binky for the destruction of Fairy World at the end of the episode.
- Trash the Set: The last day of FLARG, G, stands for "Goodbye", as after celebrating it, then the host must say goodbye to the planet they celebrated on by literally blowing it up.
- Vomit Discretion Shot: The fourth day of FLARG, R, stands for "Ranksgiving", and involves the Yugopotamian eating rank (disgusting) food (which is delicious to humans) and throwing up on the host. Since Mark's host happens to be Timmy, he ends up getting covered in alien barf.
- Xenomorph Xerox: The beings on the planet the Yugopotamians were celebrating FLARG on greatly resembled the creatures from the Alien franchise.
"Oh, FLARG."
