While hunting wild boars, Fang consistently bogarts any food she and Spear come across, causing Spear to grow increasingly agitated at her. Eventually Spear snaps and attacks Fang, losing his spear in the process, but their fight is interrupted when they wander into a den of large snakes. A flash flood rushes them and the snakes into a swampy river, where they get attacked by a giant snake (likely a Titanoboa). Fang kills the giant snake, but despite working together to stay afloat, the two fall down a waterfall, causing Spear to hit his head on the way down. Fang pulls Spear from the water, and as Spear comes to, Fang fetches Spear's lost spearhead. They reconcile and continue their journey together, now hunting food as a team.
Tropes featured in this episode include:
- Action Film, Quiet Drama Scene: Halfway into the episode, Spear entertains himself with some shadow puppetry while thinking of his children. Sadly, it turns into a nightmare flashback of a dinosaur eating the children.
- Animals Not to Scale: Zig-Zagged with the large snake, which is about the correct length for the extinct species Titanoboa, but its width makes it much bigger than the ancient snake, considering Fang bites onto it and only seems able to grab about a third of its neck.
- Artistic License – Biology: The snakes appear to be Titanoboa due to their size, but they have fangs similar to a venomous snake. And yet, they seem to be non-venomous like the real Titanoboa.
- Backing Away Slowly: After Spear and Fang actually notice the huge wall of snakes nearby, both of them have this reaction while staring in utter shock. After a few seconds of this, Fang turns and sprints away, followed closely by Spear.
- Behemoth Battle: The underwater fight between Fang and the largest snake.
- Butt-Monkey: Spear does not have a fun time in this episode. He is repeatedly deprived of food by Fang, gets an upset stomach from the one grub he does manage to eat, has his spear broken when violence breaks out between them, and when both he and Fang fall down the waterfall, he ends up hitting several rocks on the way down while the much larger T. rex lands in the water without issue.
- From Bad to Worse: What's worse than almost stumbling into an enormous mass of snakes? Getting swept up in a flash flood filled with those same snakes... which is about to go over a waterfall.
- If I Wanted You Dead...: During their fight, Fang could’ve killed Spear several times. Instead, she knocks him over and tosses him around.
- Inevitable Waterfall: While struggling against a flood filled with a horde of snakes, Spear quickly sees a waterfall with much sharp rocks at the bottom.
- Lightning Reveal: After Spear and Fang are both caught up in the river, a lightning strike illuminates the fact that they’re both surrounded by huge snakes.
- Loud Sleeper Gag: At one point, Spear is annoyed by Fang’s loud breathing and snoring nearby while he’s trying to sleep, and he chucks some debris at her.
- Kill Steal: This trope drives the conflict of the episode. Spear and Fang try to hunt together, but each time they find prey, the Tyrannosaurus takes all of it, leaving nothing for the caveman. For example, when Spear successfully kills a warthog by throwing his spear, the dinosaur gets there first and eats the warthog whole before the caveman can get a piece of it. Initially it's Played for Laughs, but soon it turns more serious and almost drives the duo apart.
- Oh, Crap!: Both Spear and Fang sport a look that personifies this when they see a wall of giant snakes right next to where they are fighting.
- Off with His Head!: The fate of the biggest snake, courtesy of Fang.
- Snakes Are Sinister: As the episode title suggests, giant snakes (likely Titanoboa) play a prominent role in the climax of the episode.
- Surprisingly Realistic Outcome: Spear's attempts at using a snake's body to hold him and Fang atop a waterfall quickly fails due to Fang's heavy weight and the snake's own smooth scales pulling Spear's grip off its body.
- Vegetarian Carnivore: Fang is shown eating fruit at one point. This is actually Truth in Television as many carnivorous animals will supplement their diets with fruit as it's easier to digest than most other forms of plant matter and contains nutrients that they'd have a hard time finding elsewhere. In fact, carnivory, omnivory, and herbivory are generally more of a spectrum than a strict trinary.
