"There will be a reckoning when we finally meet, Baron Karnor! I'm looking forward to it...!"
The Thunderkittens are out working on a map of the area when they come across a Wollo being attacked by monsters made out of stone. They do their best to help, but the creatures steal the man's purse. The Wollo explains the monsters are from the Black Tower of Robber Baron Karnor, who robs many who pass through this countryside. The kids realize that must be the tower they spotted earlier, but when they go to check it out, Wilykat disappears. Lion-O comes as soon as the sword alerts him they're in trouble, and he and Wilykit fall through the same trap door to the tower's basement. Now they have to get through the obstacle course of Death Traps to reach Wilykat, trapped in a cage at the top of the tower.
This episode provides examples of:
- Acid Pool: The second trap Lion-O comes across.
- An Aesop:Lion-O: Remember Jaga saying, "It's wise to save your money and spend it carefully. But greed can destroy you."
Wilykat: (gestures to Baron Karnor) Jaga must have this guy in mind.- And another one.
Lion-O: I guess a doesn't seem so funny, when the joke's on you. I'll have to remember that. -
Anti-Climax Boss: Lion-O spends the episode getting more and more pissed off at Karnor for putting him through Hell every time he takes a step and keeps talking about how he looks forward to finally meeting him face to face for a showdown, promising he'll make him pay for this. When Lion-O eventually finds him, it's clear that's not going to happen... - Be Careful What You Wish For: The Baron wanted to create a place that would keep his treasure safe from everyone else. Judging by all the treasure at the top of the tower, it worked. Nobody can touch his treasure... and a lot of good that does him now.
- Crazy-Prepared: Seems the Baron had set up his traps for every possible outcome that trespassers would do to avoid said traps.
- Cutting the Knot: The first obstacle is a set of trick steps. When walking or crawling up them proves too difficult, Lion-O simply uses the sword to leap over them.
- Dead All Along: Baron KarnorWilykit: Lion-O... he isn't alive!
Lion-O: No, and it looks like he hasn't been for a long time. - Dead Guy on Display: Lion-O and the Thunderkittens find the Baron's corpse sitting on a throne.
- Death by Materialism: The Baron died standing guard over his treasure.
- Death Traps: Read the title.
- Descending Ceiling: Lion-O has to get through one. He's able to buy some time by propping it up with the sword.
- Distressed Dude: Wilykat gets captured and birdcaged, requiring his sister to take a dangerous journey to save him.
- Dude, Not Funny!: Lion-O tricked Snarf into swimming by pretending to drown from a cramp. Snarf calls him out for making him worry. Lion-O realize he's right, and later apologized for it.
- Durable Death Trap: All of the Baron's traps work perfectly despite nobody being around to maintain them for who knows how long. Even the one that involves the victim falling into a giant octopus' lair.
- Dying Alone: Apparently happened to the Baron. Though the only company he had were the gargoyles he brought to life to steal for him.
- Everything Trying to Kill You: How do you want to die — mauled, roasted, crushed, skewered, or sliced?
- Evil Tower of Ominousness: Again, check the title.
- Fed to the Beast: One of the traps almost drops Lion-O into a pit with a giant octopus-like creature.
- Foreshadowing: When the sword alerts Lion-O that a Thundercat's in danger, it doesn't show him a caged Wilykat but Kit outside the tower frantically searching for him. Seems an odd definition of danger, right...? Not when you learn that the Baron is dead, meaning Wilykat's inconvenienced but not in danger since there's no one around to harm him. The sword obviously thought Kit, extremely worried about her brother, was the one in more distress.
- Furry Reminder: Wilykit purrs when she first sees the tower and makes some cat-like snarls when getting through the room of flames.
- Greed: The baron's love of money was so great that he died protecting it.
- Involuntary Group Split: A set of spiked bars drop from the ceiling, separating Lion-O and Wilykit and forcing them to take different paths to the top of the tower.
- Laser Hallway: The second trap Wilykit faces. Good thing she was smart enough to test the room first!Wilykit: I'm getting to know you, Baron.
- Literally Shattered Lives: The only way to defeat the Baron's gargoyles.
- Names to Run Away from Really Fast: "The Black Tower of Robber Baron Karnor."
- Never Say "Die": The Award for Narmiest Use of This Trope goes to — "Lion-O... he isn't alive."
- New Powers as the Plot Demands: The Sword of Omens' blade can be extended and made flexible enough to be used as a vaulting pole, apparently.
- No Ontological Inertia: Unfortunately averted with the Baron's enchanted gargoyles. They continue to come to life, steal from passersby, and attack anyone who comes to the tower, even though their maker/owner/boss is long dead and can no longer benefit from any of it.
- Palate Propping: Lion-O escapes the giant octopus by doing this.
- Shirtless Scene: Lion-O provides one when he's seen swimming.
- Slippery Skid: One of the steps in the tower is rigged this way. It's also a Surprise Slide Staircase, forcing Lion-O and Wilykit to use the Sword to jump over them.
- Smashing Hallway Traps of Doom: This is the last trap Wilykit has to get through.
- Spikes of Doom: Come from the aforementioned Descending Ceiling.
- Sticky Situation: Wilykit lands on a sticky step when she and Lion-O first try to head up into the tower from the bottom.
- Tempting Fate: Wilykit observes, "Look, Lion-O — two ramps. Which one should we take?" Cue bars dropping from the ceiling, separating the two.
- Later, Lion-O says "What's happened? No more tricks?" Cue the acid trap.
- Tentacled Terror: Lion-O has to fight a giant octopus-like monster.
- Trap Door: How the heroes end up in the tower in the first place.
- The Unfought: After everything Lion-O and the Thunderkittens went through to reach Baron Karnor to make him stop causing trouble, they find out he's already dead.
- The Walls Are Closing In: Lion-O comes to a Pit Trap he thinks he can jump. It widens while he's in mid-air. Just after he digs into the wall on the other side to stop himself from falling, you guessed it, they start closing back in.
