Nebrie are large amphibious creatures that inhabit the swampy regions of Thra. Jen falls into a bog on his quest in The Dark Crystal, after being startled by Fizzgig. Kira, able to communicate with the grub-like creatures, calls below the muck to a mother Nebrie, who lifts him out.
Skeksis consider roast Nebrie to be a great delicacy, often slaughtering the animal for their daily banquets. However the Podlings utilize Nebrie as well. The poddlings domesticate Nebrie for collecting milk. When a Nebrie died the Podlings would waste nothing - its skin would be used to make drums and the patches of fur around its face and ears would be fashioned into clothes for the little Podlings.
