The 31st episode and Part 1 of '20,000 Leagues Under Sanity'.
When Sir senses an energy signature similar to Golus underneath the Arctic seas, he sends Z-Squared, Godzilla 2000, Mr. Freeze, and Tafeli to investigate. Needless to say, they run into a Giant Jellyfish, the main characters of The Marvelous Mis-Adventures of Flapjack, confront a giant crab, and are saved by a Metal Gear RAY.
This is going to be messy, isn't it?
- Call-Back: Golus and Tafeli becoming a new member. Oh, and that time travel incident. What else needs to be said?
- Also, penguins are still the deadliest creatures Equestria knows.
- Contrived Coincidence: Z-Squared deduces that the fact that Flapjack's crew got here by use of what seems to be the Great Evil is this.
- Destructive Savior: The Metal Gear RAY certainly isn't gentle with Karkinos.

- Killer Rabbit: Not only Equestrian Penguins, but also Me'Du'Sah's Moon Jellies.
- Logic Bomb: Z-Squared suffers one when Flapjack's gang arrives.
- Mama Bear: Bubbie, as in canon.
- Mythology Gag: The final line from Z-Squared. "Oh my God. Metal Gear."
- The theme of the machine itself is 'Rules of Nature'. 3 guesses as to why?
- Noodle Incident: One particular penguin sent half of Ponyville to the hospital. Basil and Fluttershy remember this with fear.
- Not Now, Kiddo: Godzilla is ignored by everyone as he tries to warn of the upcoming burst that'll propel them upwards.
- Not Quite Dead: Karkinos, even after being blasted to hell by Godzilla and Tafeli.
- Done in another sense with Me'Du'Sah.
- Song Fic: Temporarily turns into this when Metal Gear RAY arrives.
- Traveling at the Speed of Plot: Our heroes, after an excursion with Me'Du'Sah, manage to get to the orb easily. It's not the end, though...
