In the Empire strikes back, you see the pig-like Ugnaughts. I wonder if they're related to the Gammorrean guards in Jabba's Palace. If they are related, then why did one end up having green skin, and the other pink?

The Gammorreans are from the planet Gammorr. They live in a society ruled by the female sows. They are not known for their intelligence. Ever since their planet was discovered, they have been hired as guards for several criminal organisations.

The Ugnaughts are first seen working in Cloud City, over the gas giant Bespin. Not much else is said about them.

I also read that Ewoks and Wookies are distantly related. It must be very distant, because they don't look anything alike.

Ewoks are a teddie-bearish race from the forest moon of endor. According to C3pio, they speak a very primitive dialect . The language they are speaking is unknown.

Wookies are furry humanoids from the planet of Kashyyyk. Chewbacca was a famous member of this species. They speak two languages, Shriiwook and Xixacti.

Shriiwook is the main language spoken by Wookies. Wookies cannot speak Galactic Basic, due to the shape of their throat.

Xixacti is the language of the Wookies of the Wayland Islands on Kashyyyk. It was also used by the Wookie spy organisations during the time of the Empire.
