Fuzzum language

The Fuzzum language was the native language of the sentient Fuzzums species from the planet Dandelo. As of 15 BBY, the language was intelligible to at least some protocol droids.

Behind the scenes
In the Star Wars: Droids episode "Copy and the Starhunters," the Fuzzums are shown to speak an alien language, but the language itself is never mentioned by name.
