- The Trench Dragon was released on September 8, 2016, along with the Quicksand Dragon, Bubble Dragon, Conch Dragon, and the Lagoon Dragon.
- The Anayrahm Trench in the Trench Dragon's description may possibly be a reference to the Mariana trench in the South Pacific Ocean, because when spelled backwards, it spells "mharyana." When pronounced, it sounds very similar to the word "Mariana."
- The Trench Dragon's description mentions that it "relies on its dark magic glow to shed light on the gloom of the deep sea." This may reference the fact that many deep-sea organisms possess an ability to glow, called bioluminescence, in order to survive in the dark waters near the bottom of the oceans.
