The food Kel and Elia steal from the Ugnaught food vendor in the marketplace is puffer pig bacon. Puffer pigs were introduced in the Star Wars: Rebels episode Idiot's Array (2015).
In earlier versions of the script, Kel and Eila were named "Bo" and "Dopa," which is "one" and "two" in Huttese.
The Chelidae species that work as the engineers on the Colossus are named after a family of real-world turtles. They are designed to be the indigenous sentient species of the water planet Castilon where the Colossus resides.
