After falling into the ocean, Bean, Luci, Zog and Elfo find themselves in an underwater castle inhabited by sea trogs, who seem friendly to the humans at first but have sinister plans for them.
Tropes
- Back for the Dead: The Land Vikings survived their fall into the ocean from part 1, only to be kept alive in the underwater castle until they are killed on-screen by the parasite.
- Big Damn Heroes:
- Oona breaks into the underwater castle to rescue Bean, Lucy Elfo and Zog, just as Bean is about to be infected with a parasite, flooding the castle in the process.
- Mora breaks through a window to save Bean from drowning.
- Black Comedy Cannibalism: The Sea Trog chef serves the main characters his cousin Roger.
- Blatant Lies: Elfo insists the Sea Trog larvae don't hurt, but the several seconds of pained screaming when he puts on in his ear proves otherwise.
- The Bus Came Back:Some of the vikings from Part 1 return, as prisoners of the sea trogs.
- Creepy Monotone: Luci, Elfo and Zog while they've got Sea Trog larvae in their heads.
- Cut a Slice, Take the Rest: Though not with a cake; when the sea trogs bring their guests their meal, cousin Roger, Zog gives Bean the head, and keeps the rest of the dish for himself.
- Drowning Pit: The underwater castle inadvertently becomes one after Oona breaks a ceiling window.
- Dying Declaration of Hate: Stryker's last words are telling Bean to tell Turbish he hates him.
- Eye Scream: Sven the Land Viking's eyes explode and larvae pour out of them.
- Freeze-Frame Bonus: Before entering the underwater castle, a mermaid version of Dr. Zoidberg from Futurama can be briefly spotted inside a wreck.
- Help, I'm Stuck!: At the start of the episode, Bean is still trapped in the tiny door. Elfo and Luci have to break the wall around it to free her.
- Groin Attack: Luci's body, after being decapitated again, does this to Elfo.
- Insistent Terminology: Luci calls Elfo's balls "grapes". Elfo indignantly retorts they're not that small and demands he call them plums instead.
- Internal Reveal: Elfo, Bean and Luci learn about Zog's ancestors stealing Dreamland from the Elves, as Zog knew about this all along (though he believed it was just a fairy tale).
- Killed Off for Real: Stryker, as he gets infected by the sea trog's parasites.
- Kleptomaniac Hero: Zog and Elfo waste no time trying to steal the treasures in the underwater castle. Bean calls them out for it.
- Kryptonite Factor: Mercifully, Sea Trogs are vulnerable to sunlight. Even a host just being exposed to sunlight kills them.
- Losing Your Head: Luci again, and the sea trog chef's cousin Roger who's still alive after being carved up and served.Bean: "Is it just me, or did dinner blink at me?"Roger's head: "Psst, I'm still alive, smuggle me out in your large intestine."
- Nobody Here but Us Statues: Elfo tries to pretend to be a statue to hide from the sea trogs, and suggests Bean does the same. Bean calls him out on how ridiculous he is looking.
- O.O.C. Is Serious Business: Zog, Elfo and Luci all start acting way out of character when infected by the parasites, like Zog willingly giving back the gold he stole. For Bean, it's a sign her friends are already infected.
- Parasitic Horror: The mating ritual of the Sea Trogs involves putting their larvae into human hosts, where they grow and eventually kill the human.
- Parental Title Characterization: As a sign of just how spooked she is about impending drowning, Bean calls out for her "daddy" and "mommy" to save her.
- Remembered I Could Fly: Luci remembers he has wings while falling, but then Bean grabs his tail before he can fly away from them.
- Tempting Fate: When his effort to free Bean doesn't work, Luci declares she's stuck forever. Cue the ground giving way beneath the trio.
- This Means War!: Elfo's response to learning the history of Dreamland and how it was taken from the Elves.
