Tri-Stone Area

Whoa, whoa, whoa. So-- so they're just gonna be talking in "cave-talk"?

It’s the Stone Age and Phineas and Ferb are cavemen who decide to invent something new, fun and useful... the wheel! Meanwhile, Dr. Doofengung attempts to make his digs more upscale by using the precursor to the Inator device... a plain old stick.

Episode Summary
In 27,000 B.C., Phinabunk and Gerb (caveman versions of Phineas and Ferb) go through their stone-carved blueprints in the backyard and decide to make a wheel.

'''Dan Povenmire shows Jeff "Swampy" Marsh his storyboards for the caveman episode, and explains that all of the characters will speak in a nearly incomprehensible cave-talk and Doofenshmirtz will just grunt. They both agree that they will explain the premise in a low budget live-action photo animation when needed, so the audience won't get confused. Swampy then asks Dan where Perry is.'''

Bunka (Perry), a platypus-like animal with frilly spiked fur, a big brow, long canines, and red spines on his tail, is briefed by Monobrow, and a monkey named Gnarl. Monobrow explains to Bunka that Doofengung is planning something that Bunka should thwart. After briefing Bunka, Monobrow accidentally slips on one of Gnarl's banana peels.

Da and Mog say goodbye by smelling each other's armpits before Da goes out to hunt. Mog then notices her messy hair in the mirror, and decides to go to Bobbi's to get it done, putting Can-tok in charge by presenting her with a staff as she leaves. Can-tok tells Phinabunk and Gerb that she's in charge before going to communicate with Stacy long distance by using the vibrations of a log. Outside, a pile of rocks are delivered to Phinabunk and Gerb, who tell Isabelock, Boofgard and Baljug to make a wheel out of one of them, though it takes a few tries for them to get it right.

At Doofengung's cave, a neanderthal-esque Doofenshmirtz entertains himself by watching water droplets slowly drip from a stalactite. Bunka crashes through the stone wall and Doofengung traps him in a bone cage. Doofengung explains that Roger, a human who is apparently a step ahead of him on the evolutionary chain, is living luxuriously while Doofengung lives in a dirty cave. Doofengung states that it is unfair, and begins to throw a fit.

'''Dan decides that the caveman episode was a bad idea, but Swampy, who has become interested, takes over. Swampy explains to Dan that Phinabunk and Gerb had completed their design of the wheel, and present it to their friends.''' Can-tok notices them playing with their wheels outside, and runs off to inform Mog. Phinabunk realizes that the four wheels can be put together to pull a single vehicle, and the children decide to construct one.

Meanwhile, Doofengung shows Bunka his Stick-inator, explaining that he plans to poke a mammoth with it, causing the mammoth herd to rampage through Roger's territory, scaring him off so Doofengung can go claim it. Dan translates Doofengung's plan for the audience.

As Can-tok walks home, disappointed that Mog would not listen to her, she runs into Phinabunk, Gerb and the others in their new car-like vehicle constructed with rock and wood. She pursues them, but is momentarily distracted by Jerabunk. Phinabunk and Gerb's vehicle rides past Conk, who's foot is frozen to a glacier. As Can-tok chases after Phinabunk and Gerb, she is picked up by a vulture and carried off to an active volcano. Can-tok hits the vulture with her staff, causing it to drop her near the lava, which burns the tip of the staff.

At the same time, Doofengung uses his stick-inator on one of the mammoths, though his plan backfires as the mammoths turn around and chase him. As Doofengung runs past Phinabunk and Gerb, the mammoths stampede over the vehicle, completely crushing it before Mog can see it. Can-tok waves her staff in frustration, and it suddenly sparks fire. As the mammoths crush his cave house, Doofengung curses Bunka, who walks past him, still in his bone cage.

Dan and Swampy realize that they forgot to put a song in the episode, and begin to write one while dancing. Phinabunk, Gerb, and all of their friends and family gather around Can-tok's fire and begin to sing a caveman version of Gitchee Gitchee Goo in celebration.

Background Information

 * The episode takes place in 27,000 B.C.
 * The episode starts without an explanation why the story plays in the past.
 * No one time travels, as the characters are from that period.
 * ScriptTriStone.jpg none of the characters speak English, this episode is probably hard to understand on its own. However, a long-time viewer may pick up on the equivalents of catch phrases like "A platypus? ... Perry the Platypus!", "Behold, my ...inator!", "Aren't you a little young ...", and such. Furthermore, some words are repeated through the episode, and some are rather similar to English words; examples: "ni" is "no", "in charga" is "in charge", etcetera. In 2014, Robert Hughes uploaded to twitter a script that proves this.
 * When we see Phinabunk feeding stone tablets to Bunka, it reflects how real platapi eat, using rocks in their mouth to chew their food.

Production Information

 * Description of the video:
 * This video shows exactly what it's like working on Phineas and Ferb. It's 8 O'Clock at night, and Celeste, Martin and I are recording a demo for a Caveman version of Gitchee Gitchee Goo for an upcoming episode.
 * A sneak peek of this episode was shown on July 22, 2011 at the San Diego Comic Con.
 * This episode was aired in Disney Channel On Demand on January 6, 2012.
 * It is unknown why the episode does not have the Disney Channel Original logo tagged at the end when it airs without "Doof Dynasty".
 * This is the first episode aired in 2012.

Errors

 * In some scenes, Gretchen is not wearing her glasses when Roger, Carl, and Bobbi are all seen wearing their glasses.
 * Before the song Zubada starts, only Phinabunk, Gerb, Can-tok, Bunka, Isabelock, Boofgard, Baljug, Jerabunk, and Mog and Da were seen but then, the Caveside Girls appear out of nowhere.
 * When Phinabunk sings the line "Ooh chaka ooh chaka" in the song, Gerb's nose briefly turns into an outlined square.
 * The first time Katie is seen, she does not have sandals on. The second time after, she has sandals.
 * When the mammoths trample Doofenshmirtz house, they go from left to right. But in Doofenshmirtz plans, Roger's house was on the left of Doofenshmirtz house. The mammoths would have to trample Roger's house too, which would have made Doofenshmirtz's plot a success.

Continuity

 * When Can-tok tells Phinabunk and Gerb that she is in charge, Phinakbunk looks confused, points at the sky and asks,"Can-tok in charga? Du mhakka satellakkah?" This is a reference to when Candace would be in charge if a satellite crashed into the house.("Rollercoaster")

Allusions

 * The Flintstones - Isabelock having a bone in her hair is most likely a reference to Wilma and Pebbles Flintstone, as they both have bones in their hair. All human characters walk around barefoot, much like most characters from The Flintstones. The Tri-Stone Area is also a parody of Bedrock.
 * Daffy Duck and the Dinosaur - The Tri-Stone Area is similar to the 1939 public domain Daffy Duck cartoon.
 * Quest for Fire - This 1981 film featured cavemen talking in their own language.
 * Caddyshack - Carl Spackler in Caddyshack claims to have golfed with the Dalai Lama. He says the Lama told him "Gunga galunga... gunga, gunga-lagunga" which sounds very similar to how Caveman Monogram talks.
 * SpongeBob SquarePants - This episode is quite similar in structure and theme to the episode Ugh, which includes real-life segments and presents the caveman counterparts of the regular characters, caveman language and the discovery of fire. SpongeBob was SpongeGar and Patrick was Patar.
 * The Cat in the Hat - Bunka da bunkaquan (Platypus in a hat?) could be a lose play on phraise from "The Cat in the Hat" where the kids say "He's a guanka in a bunkaquank" in Eskimo.
 * Tuukka Rask - The word tuka comes from the name of NHL hockey goaltender, Tuukka Rask, from the Boston Bruins.

Trivia

 * Dan Povenmire and Swampy Marsh make an appearance in this episode, in stop-motion.
 * Milly is not seen when the Caveside Girls first appear.
 * This is the first episode where, for most of the episode, the characters don't speak English.
 * There is a caveman version of the Quirky Worky Song.
 * This episode may have explained how Conk ended up frozen in an iceberg in "Boyfriend From 27,000 B.C.". Conk became distracted while the boys rode by, and the wall of ice snuck up on him and trapped his foot. (The theory is that the ice age caused a great wall of ice to slowly travel across the world.)
 * This is the first episode to show Gretchen and Adyson without glasses and a hairband respectively.
 * Katie is shown wearing sandals during the song, the only footwear worn by any of the main cast.
 * First time Katie is seen with loose hair.
 * When Can-tok runs through the bushes, her hair is briefly changed to the way Candace's hair looks.Canduk_with_Candace's_hairstyle.png
 * The fourth wall is broken when Dan says Swampy's part of the episode is hard to understand, and Swampy says that's a good reason why they're doing the stop-motion pictures showing themselves in the episode.
 * This is the fourth time cave-people are seen. Previously were in "Boyfriend From 27,000 B.C.", "It's About Time!", and "Rollercoaster: The Musical!".
 * Isabella expresses annoyance with others use of her catchphrase again ("Out of Toon", "Phineas and Ferb Christmas Vacation!", "Suddenly Suzy").
 * During the photo animation scenes, the Perry the Inaction Figure was seen. ("Toy to the World")
 * Also in the photo animation scenes, a picture of Phineas and Ferb in underwear is seen. ("Out to Launch")
 * Conk reappears ("Boyfriend From 27,000 B.C.").
 * Second time a live-action character is used, first was Ashley Tisdale in "Lights, Candace, Action!".
 * Bobbi Fabulous makes a cameo, again as a hair dresser ("Dude, We're Getting the Band Back Together").
 * The SUV that was in "Finding Mary McGuffin" and "The Secret of Success" appeared on a stone-print.
 * Second time Phineas and Ferb/Phinabunk and Gerb make a new language ("Ferb Latin").
 * Second time Jeremy and Candace look like cave-people ("Boyfriend From 27,000 B.C.").
 * Third time Doofenshmirtz brings up evolution. ("Phineas and Ferb Hawaiian Vacation," "Brain Drain")
 * Second time 27,000 B.C. is brought up ("Boyfriend From 27,000 B.C.")
 * Second time Perry does not escape from his trap. ("Lotsa Latkes")
 * Doofenshmirtz uses the famous illustration, "The Ascent of Man," in his presentation as he had done in "Phineas and Ferb Hawaiian Vacation." Also, as in Hawaii where Perry had a party on the deserted isle while Doofenshmirtz suffered, Roger Doofenshmirtz parties in pre-historic Danville while Doofenshmirtz complains about his living accommodations.
