- Aristocrats Are Evil: The Countess, though she thinks she is helping the TARDIS.
- Arson, Murder, and Jaywalking:
The Doctor: Why should I help you? You nearly wrecked my TARDIS, you unleashed a carnivorous interdimensional... You've done a lot of bad stuff. I'm not even sure I like you very much.
- Call a Smeerp a "Rabbit": The Doctor warns Bernice for a Lion, though he then says "Sort of" and describes it's green and has more fangs.

- Invisible Monsters: The Doctor can't see the creature in the Tardis, but everybody else can.
- Killer Robot: The IMC Mining Robots double as these.
- Living Ship: Emphasis is put on how the TARDIS is alive. And a she.
- Noodle Incident:
Benny: This isn't the first time I've been trapped in a slowly collapsing bubble of reality. Hell it's not even been the second.
- Shout-Out: When they are drawn back in time the Doctor says it is very The Lion, the Witch and the Wardrobe.
- Stable Time Loop: The Doctor getting sent into the past and dropping his TARDIS Key leads to it being found in the future and drawing him there.
- Tempting Fate:
The Doctor: We're safe.
- Too Spicy for Yog Sothoth: The 5th Dimensional "Vortex Shark" spat the Doctor out and left the time bubble, in the end.
- Well-Intentioned Extremist: The Countess really thinks she is helping the TARDIS in trying to separate its telepathic link with the Doctor.

- I Am Not Shazam: Mocked when the Doctor says Frankenstein is the name of the Monster, not the Doctor, as his mutated future self calls himself Frankenstein.
