Things were not going so well for the gang. The crash had damaged the van and the time machine was not working properly. A really scary thought was that they had no idea how Le Paradox managed to develop his own time machine. They needed to figure out a way to solve these issues, or they would have to get used to permanently living in a cave.
After freeing Bob, Sly brought him back to the safe house, where he took an immediate liking to Bentley's gadgets. He then explained how Grizz stole all of his eggs. Bob eventually became depressed and fell into a slump. He also gotten out of shape, allowing Grizz to capture him and also steal his cane. The gang needed to figure out what type of operation Grizz was running for Le Paradox, and why it involved stealing all of the eggs.
Tropes:
- All Cavemen Were Neanderthals: Bob is a prehistoric raccoon. Instead of the sleek physiology that Sly and his other ancestors share, he is large, muscular and less handsome than them. No more hairy, though.
- Anachronism Stew: The level is clearly set in the Ice Age, with the enemies being wooly mammoths, sabertooth tigers and dodos, and yet dinosaurs are around also, the plot centered around the theft of dinosaur eggs. Considering this is set in an Alternate Universe where anthropomorphic animals populate the earth instead of humans, this could be less ridiculous than one thinks at first glance.
- Anachronistic Animal: Despite the level being set during the Ice Age, with anthropomorphic mammoths, sabertooth tigers and dodos being the enemies and a neanderthal-esq species of raccoon is an ally, much of the level has various species of dinosaurs appear as fauna, with dinosaur eggs being a recurring MacGuffin in the plot.
- Arc Hero: Bob is the Guest-Star Party Member of this timezone.
- Arc Villain: The Grizz
- Bad with the Bone: Bob's "cane" is outfitted with a curved bone at the end. Having been stolen by the Grizz, Bob settles with using a bone club.
- The Cameo: After talking with Bentley in "Stone Age Reconnaissance", look on the top of the waterfall and you can see Clockwerk. Later, you can see him again in "Starving Starving Hippo"; before you start to go after the penguins, look up high and Clockwerk is perched on top of a large dinosaur tail bone.
- Cell Phones Are Useless: When Sly is tailing The Grizz, he is speaking with Le Paradox on his phone, much of it involves him having a hard time hearing him due to bad reception. Considering the phone is able to make calls through time by millions of years and was made using a fairly new form of science, this is understandable.
- Contrived Coincidence: The fact that Murray's aboriginal necklace sent the Cooper Gang in an era where one of Le Paradox's mooks is stationed at is a complete coincidence.
- Downer Beginning: The episode starts with the van and the Time Machine out of commission, the Cooper Gang (with Carmelita) trapped in the Ice Age.
- Dumb Muscle: Being a raccoon caveman, Bob lacks a lot of the finesse his descendants have and is mainly just Murray if he could climb. Understandable, since he predates the Thievius Raccoonus and all of its tricks and his body had evolved for the harsh conditions of the Ice Age, unlike the sleek and nimble CE raccoon.
- Even the Subtitler Is Stumped: While most of Bob's dialogue has subtitles, it just says "gibberish" when he says his name.
- Foreshadowing: Bentley notices that there is an (albeit primitive) conveyer belt system in the general area, hinting that something is off. Not only that, but the best vantage point to photograph it is on The Grizz's ice statue.
- Gratuitous Rap: The Grizz almost speaks entirely in impromptu rap.
- Jaded Washout: With The Grizz being responsible for all of the eggs being gone, Bob became a failure as his tribe's chief food provider and ate himself into a downward spiral before The Grizz captured him.
- MacGuffin: The Grizz's Cool Crown is revealed to have been an artifact that the Gang uses to travel to their next destination.
- Mammoths Mean Ice Age: The flashlight guards are all anthropomorphic wooly mammoths.
- Mood Whiplash: After beating Toothpick, the Cooper Gang and Carmelita have just become stranded in the Ice Age with possibly no chance of escaping pre-history... and then the Grizz is spotted during the recon mission; a giant black bear in a garish purple outfit, wearing a crown and speaking through rap.
- Non Sequitur: Throughout the level, the Grizz is established as a wannabe artist who's plans revolved around forging cave paintings by stealing eggs in a Time Travel for Fun and Profit gambit... and when he is confronted by Murray, the Grizz starts waxing on about how he always wanted to be a figure-skater and accuses them of getting in the way of that, something that wasn't mentioned once until now. Even Murray is perplexed by this.
- Noodle Incident: Murray also claims that he won both a sumo wrestling competition, and then a ramen eating championship afterwards.
- Prehistoria: Gungathal Valley is set in 10,000 BC Australia. It has mammoths, sabertooth tigers, pterodactyls, tar pits, lava pits and the raccoon equivalent of Homo erectus.
- Shout-Out: When Murray gets separated during their final operation in the level, Murray remarks how he shouldn't have taken that left turn.
- Skin Walker: Sly's sabertooth skin costume he gets from The Grizz's room allows him to pounce on enemies and fake animals from a distance, complete with a menacing roaring noise.
- Stone Punk: Since the level is set in the Ice Age, all of the architecture in the level is all either naturally occurring or was engineered with animal bones, pelts and rocks.
- Sumo Wrestling: One of the training excersizes in "Getting Stronger" involves Bob Sumo Wrestling a penguin. Yes, really.
- Time Travel for Fun and Profit: The Grizz's plan is to steal dinosaur eggs and use them to make paint. The Grizz then makes cave-paintings with them and then "discover" them in the future and make a fortune off of it.
- Training Montage: "Getting Stronger" is basically this for Bob, with Murray as his coach.
- Ur-Example: The game openly implies that Bob is the first Master Thief of the Cooper Clan, his crude egg-hunting tool being the first Cooper cane.
