The next episode of Star Wars Rebels will be titled: The Mystery of Chopper Base. This episode seems interesting as the description is:

Kanan, Ezra and Ahsoka prepare to depart to unravel Vader’s secret, while the rebels find a way to fend off the predatory creatures that occupy the planet

This clip shows Rex and Sabine dual wielding their blasters while fending off some new creatures. Check it out below. I can’t wait for this episode.
