- Herbivores Are Friendly: Subverted with extreme prejudice: the mammoth may be an herbivore, but it is both scared and very pissed off and utterly wrecks the highway it is on, and kills at least one person.
- Stock Dinosaurs: Played With: While a mammoth shows up in this episode, it's a hairless Columbian Mammoth, rather than the more well known Wooly Mammoth.
- Oh, Crap!: Lester's reaction to learning that the anomaly has opened on a very crowed highway, as it is the worst case scenario for the team (it's a large, dangerous animal ending up in an area with many innocents bystanders, and the mammoth is NOT friendly at all).
- Wham Line: "A Mammoth on the M25!"
- Wham Shot: After leads captures the team, he leaves them trapped in a laser surrounded pen. The lights then come on.....revealing they are in a room filled with similar pens containing a hoard of creatures from all of the anomalies they've dealt with.
