On a wall in the Statue of Liberty is written "Venkman was here". This refers to Peter Venkman of the Ghostbusters, who commandeered the Statue of Liberty in Ghostbusters II (1989).
The headlines on the paper feature:
- "Dinosaurs Seen in Sewers!" the episode title
- "Man who Did Not Sleep for 40 years", which alludes to the events of In Dreams (2014)
- and "Bigfoot and I are expecting", which alludes to the events of A Foot Too Big (2014)
In season three as Zog approaches for the first time, sewer water ripples in the same fashion as the T-Rex approach in Jurassic Park (1993). Zog's growls are also similar to the iconic T-Rex roar.
The final battle takes place at the Statue of Liberty. This is a homage to X-Men (2000), where the final battle was at the same place.
In the box of Zoh's gear they find on the top of the Statue of Liberty, there is a Nintendo Advantage. This is referencing Ghostbusters II where they used the NES Advantage video game controller to pilot the Statue of Liberty.
