All the animal crates seen at the Lau spaceport bare the warning "Caution! Volatile contents" in Aurebesh.
A porg can be heard screeching from one of the many animal crates in the last act.
When Omega uses a control panel at the spaceport to create a diversion, the Aurebesh text on screen translates to "Unlocking all cargo".
The Aurebesh text on the monitor Crosshair is sitting at inside the transport shuttle at the start reads "power" and "caution", "caution".
