RA-7-81, the inventory droid in the science vessel, is a similar model to one seen in a previous animated series: AP-5 from Star Wars Rebels. And like AP-5, RA-7-81 is also voiced by Stephen Stanton.

The pneumatic tube system Omega travels through is used in part for transporting items around the Tantiss facility.

While sneaking through the Tantiss facility, Omega spies the zillo beast, which was said to have been brought there in Season 2’s “Metamorphosis.”
