Brian Henson welcomes 10 talented creature designers to Jim Henson Studios for their first Creature Brief: design and build an original underwater creature for a screen test on the Henson Soundstage.

The creature designers tackle sculpting, molding, and mechanizations as the Henson classic The Dark Crystal inspires re-imagined Skeksis who return to the castle for a screen test with the original Dark Crystal.

The creature designers breathe life into unconventional materials from a junkyard to create a believable half scrap, half fantasy creature trapped inside a hanging cage.

Humor is the key to this week's Creature Brief as mounted creature heads in an enchanted trophy room return to life under the spell of a wizard, played by Scrubs' Donald Faison.

An appearance by Lady Gaga's unicorn inspires the creature designers to create a larger-than-life creature with realistic movement, performed on a black light soundstage.

The Henson Soundstage is transformed into a mystical swamp for a screen test revealing camouflaged creatures hiding in plain sight. Face Off's Neville Page guest judges.

Gigi brings Farscape co-star Rygel into the workshop as inspiration for the creature designers to build original alien species attending an intergalactic press conference. Men in Black director Barry Sonnenfeld guest judges.

Season one finale. The three finalists are tasked with creating a creature that will interact in a scene with others and must include a prop and a special effect. The setting is a roadside tavern where their three strange creatures will meet and share their stories. Eliminated competitors return to help the finalists complete their biggest challenge yet.
