Spear and Fang set off across the sea to save Mira from her mysterious captors.
This episode features the following tropes:
- Always a Bigger Fish: Literally, since one of the pterosaurs that was harassing Fang and Spear gets eaten by the megalodon.
- Call-Back: Spear lures Fang on the raft with a handful of large grubs, the same way Mira persuaded her to climb a cliff in "Slave of the Scorpion".
- Darkness Equals Death: Played With, as Spear and Fang's nighttime encounter with a bunch of whales and hearing their echoing cries in the darkness of the ocean, unable to make out more than a few feet around them, highlights their unease with being unable to make out the beasts, even when one of them passes a few feet below their raft. Similarly, the deeper stretches of the ocean at a lower depth than light can easily reach highlights how vulnerable Spear is when he goes diving in search of food. However the climatic encounter with the Megalodon is mostly brightly light by the red sunlight and the lighting flashes of the storm, enough for Spear and Fang to make out their attacker from several meters away and prepare as best they can for it's attacks.
- Didn't Think This Through: It becomes bluntly clear that Spear didn't put much thought into following Mira beyond the immediate short-term methods of pursuing her over water, and even that occurred after he tried to physically swim after her and was overcome by the ocean currents, nearly drowning in the process. He manages to build a large raft with Fang's aid and coerces her onto it with grubs, but he takes no food supplies beyond that, and no means of fishing or procuring food from the ocean. Mid-way through, Spear's attempts to search for food in the ocean surrounding them and finding nothing makes it clear that he'd never even been near the ocean, or understood how wide and vast, yet empty, stretches of it can be. The duo are able to survive with some lucky ocean encounters from nearby sealife, but Spear is incredibly lucky they did so, or Fang might have turned on him in hunger. Beyond all that, it's also made clear he has no idea how to navigate a boat by the stars, or any concept of sailing beyond lashing a bunch of logs together into a crude raft and pushing for the majority of their trip.
- Downer Ending: Fang and Spear's raft is attacked and destroyed by a megalodon, and whilst they manage to drive it off, the storm surrounding them washes both away without a stable footing. Fang awakens on a beach on the other side of the ocean, but with no sign of Spear's whereabouts.
- Food as Bribe: Spear convinces Fang to get on the raft by offering her grubs.
- Genius Bruiser: Spear is able to come up with the concept of a crude raft lashed together from a bunch of nearby trees as a means of following Mira after seeing a leaf floating on the water, despite the rest of the episode making it clear that he'd never been anywhere near the ocean or has a firm grasp of the concept of sailing in general.
- Getting Eaten Is Harmless: The megalodon devours Spear, but since he's so small compared to the giant shark, he ends up in its mouth unharmed and free to swim around. He can easily escape when the shark opens its maw to devour Fang, though he is in danger of drowning from the seawater still located inside it's mouth and with no air pockets to use.
- Immediate Sequel: The episode picks up right where the Season 1 finale left off with Mira being taken by the ship.
- Improvised Weapon: Spear is no stranger to making use of whatever tools he can, but when the Megalodon attacks, the lack of available resources in the ocean forces him to fight back with pieces of their splintered raft after it's shattered by the beast, even using an appropriately-sized sliver as a makeshift spear to impale its eye when it flings him into the air and force it to stop attacking them.
- Nothing Is Scarier: Despite the audience being aware of their non-threatening nature, Spear and Fang are visibly unsettled by their nighttime encounter with a bunch of whales, due to being basically blind in the darkness and only able to hear their eerie cries to each other, eventually huddling down in silence together to avoid being noticed after their attempt to scream/roar their visitors away in intimidation has no effect. Beyond that, the biggest threat to the duo throughout the episode is simply the absolute lack of anything in the ocean, with vast stretches of it containing no predators at all...and no food or resources either can use beyond what they have on the raft. Spear is severely disadvantaged for most of the episode because his usual ingenuity is handicapped by having little to nothing to work with on the empty ocean.
- Say My Name: Spear saying and then shouting Mira's name in anguish. However, he quits this after washing up on the beach and goes back to animalistic grunts and vocalisations with Fang for the rest of the episode.
- Shout-Out: The way Spear defeats the Megalodon is very reminiscent of the way Jonas Taylor killed the same creature in The Meg.
- Shown Their Work: The ornithocheirid pterosaurs not only possess pycnofibres, but also plunge-dive to catch fish like real-life piscivorous pterosaurs.
- Threatening Shark: Spear and Fang get attacked by a megalodon.
