When the team crash lands on an ice moon along with a pair of aggressive aliens, they must put their differences aside to survive.
- Amazon Chaser: Raph.Mikey: Wow, you really have a crush on that salamander hottie? She's like bigger, stronger, and probably a better fighter than you.
Raph: Exactly. What a woman. - Beware My Stinger Tail: G'thraka has a spiked ball at the tip of his tail which he uses as a weapon.
- Breath Weapon: The Ice Dragons have cold breath.
- Call-Back: When the Salamandrians first appear to the Turtles, Leo calls them "Newtralizers".
- Culture Clash: The captain was willing to cooperate with the turtles, but then Leo offered a handshake (which is a sign of aggression to Salamandrians.)
- Death World / Slippy-Slidey Ice World: The frozen moon our heroes are stranded on lacks a breathable atmosphere, and has an average surface temperature of -180° Celsius. Even in their high-tech EV suits, the turtles, April and Casey are in danger of freezing to death, if they don't run out of oxygen first.
- Foot Popping: From Raph.
- Fourth-Date Marriage: Raph and Mona's romance buds rapidly within the span of the episode.
- Harmless Freezing: The Ice Dragons' Breath Weapon has this effect.
- Honor Before Reason: Both Salamandrians show shades of this, between Sal Commander wanting to dig the turtles out of the rockslide to continue the fight, to Mona constantly refusing to work with the beings who prevented their fight with the Triceratons (though, granted, she actually suspected them of working with the Triceratons at first.).
- Love at First Punch: Raph is smitten with Mona Lisa when he sees what a keen fighter she is. Which she demonstrates by beating up Raph and his brothers.
- Macguffin: The Triceraton space mine.
- Mythology Gag: Calling Y’Gythgba Mona Lisa, as well as being a love interest to Raph.
- Not So Weak: The Fugitoid may look harmless but he has a built-in blaster that kept Mona Lisa and her comrade away.
- Our Dragons Are Different: The ice dragons, who are the antagonistic force in this episode.
- Reasonable Authority Figure: Sal Commander comes to respect the Turtles almost the moment he lays eyes on them, and proposes a truce - only for Leo to mistakenly initiate a fight thanks to their Culture Clash. Later, Leo actually averts this and vehemently refuses trying to make a truce again.
- Shout-Out:
- Mikey considers calling Sal "G.I. Lizard," before settling on "Sal Commander".
- "I have a bad feeling about this.".
- Single-Biome Planet: The turtles and the Salamandarians were stuck on a ice planet and had to work to survive.
- Tsundere: Mona Lisa certainly gives out the vibes of one.
- The Unpronounceable: The heroes are unable to pronounce the Salamandrians' names, so they just call them Mona Lisa and Sal instead.
- Your Normal Is Our Taboo: Sal Commander takes grave offence at Leo offering an extended hand as a gesture of friendship. Turns out Salamandrians consider an extended hand to be a declaration of aggression.
