Koda has flashbacks in his dreams to when he first found the blue Energem. During that moment, a smilodon (sabertooth tiger) was getting ready to attack his little brother Taku, who is yelling out to him. Koda raced out and tackled the smilodon off a cliff edge, the two falling into the ocean. As Koda falls, the blue Energem glows, covering him in energy.
Koda is suddenly woken from his dream by a strange growling sound. Grabbing a log, he heads out ready to fight... Only for the sound to be coming from Kendall's newest invention - Dino Cycles. Koda, being a caveman, relies on his instincts more than most, so any strange noise is likely to be a danger to him, from the bikes, to Shelby's poor phone.
Chase offers to teach Koda how to ride a bike, claiming to have ridden everything from motorbikes to kangaroos, despite kangaroos not being native to New Zealand as Riley quickly points out. Cut to a scene in the park where Koda is attempting to ride a bike, and a children's training bike at that.
Up above, Sledge has had Wrench work on a playmate named Curio for Poisandra to spend time with while he collects the Energems. He sends a cage monster, Slammer, to kidnap the rangers and take the Energems. Slammer ambushes Chase and Koda, with Chase getting captured immediately. Koda is able to deflect the cages, until his attention is turned to a bystander who could be hurt. He dives to knock the boy out of the way, but the pair are captured instead, the boy breaking his leg in the process.
Lucky for Koda, the boy's bike was taken too, leaving a hole in the cage that the pair can escape from. Koda manages to make a torch pretty quickly, impressing both Chase and the kid, who says his name is Peter. Koda makes a splint for the Peter's leg, before heading towards the cave exit to get him some help.
Back at the Dino-Byte cafe, Shelby and Kendall are getting worried about Chase and Koda's absence, and send Riley and Tyler on the Dino Cycles to investigate. The pair find a strange signal emanating from a beachside cave, and deduce that the other rangers are being held there. Shelby and Kendall meet up with the guys outside, only to see Koda racing out of the cave with Peter in his arms. As Kendall drives Peter to the hospital, the rangers face off against Slammer, both on the ground and in the Megazord, even utilising the Stego-Raptor formation to finish him off.
After all is said and done, Koda and the Rangers find Peter, having had his injury treated, regaling his friends of his adventure with Koda. Peter than thanks Koda for his help before offering to teach him how to ride a bike, an endeavor that Koda finds himself much more successful at this time around.
Tropes used in this episode:
- Artistic License – Physics: You can't grab a random stick and set it one end on fire to make a torch; you'd end up with a stick on fire. The distinctive "flaming torch" bloom of flame comes from the end of the stick being wrapped in oil-soaked cloth.
- Butt-Monkey: Shelby. She seems to be taking the brunt of the jokes and negativity this season, which in it's own weird way is an awesome first for female cast members. This time, almost immediately after sticking up for Koda and showing her understanding of why he was spooked by the sound of the motorcycles, her phone rings not twice before Koda strikes it with his log, causing it to smash into the floor and breaking it into its component pieces. Chase immediately mocks her previous statement of being understanding, to boot.
- Human Popsicle: The first scene implies that the blue Energem was able to put Koda into stasis when he fell into the ocean 100'000 years ago. It would also explain why he has had so much difficulty in adjusting, especially if his defrosting was only recent. A quick line from Koda in the following episode confirms this.
- Mix-and-Match Man: Curio, who was created from spare monster parts.
- Reckless Gun Usage: Sledge launches Slammer's space pod by shooting the launch button with his beam gun.
- Reverse Grip: Riley prefers holding his sword in a reverse grip like Antonio.
- Wardens Are Evil: Slammer has this vibe. He even has a prison guard's hat.
