Tri-Stone Area

Woah, woah, woah? 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. Doofenshmirtz 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., Phinebunk 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. 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.'''

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

Caveman Lawrence and Linda say goodbye by smelling each other's armpits before Lawrence goes out to hunt. Linda then notices her messy hair in the mirror, and decides to go to Bobbi's to get it done, putting Canduk in charge by presenting her with a staff as she leaves. Canduk tells Phinebunk 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 dilivered to Phinebunk and Gerb, who tell caveman versions of Isabella, Buford, and Baljeet 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 stalagmite. Perry 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 Phinbunk and Gerb had completed their design of the wheel, and present it to their friends.''' Canduk notices them playing with their wheels outside, and runs off to inform Linda. Phinbunk realizes that the four wheels can be put together to pull a single vehicle, and the children decide to construct one.

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

As Canduk walks home, dissapointed that Linda would not listen to her, she runs into Phinbunk, Gerb and the others in their new car-like vehicle constructed with rock and wood. She persues them, but is momentarily distracted by Jerbunk. Phinbunk and Gerb's vehicle rides past Conk, who's foot is frozen to a glacier. As Canduk chases after Phinbunk and Gerb, she is picked up by a vulture and carried off to an active volcano. Canduk wacks 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 Phinbunk and Gerb, the mammoths stampede over the vehicle, completely crushing it before Linda can see it. Canduk waves her staff in frustration, and it suddenly sparks fire.

As the mammoths crush his cave house, Doofengung curses Perry, 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. '''Phinbunk, Gerb, and all of their friends and family gather around Canduk's fire and begin to sing a caveman version of Gitchi Gitchi Goo in celebration.
