JIM HENSON'S CREATURE SHOP CHALLENGE

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 are given the chance to reimagine the fictional species Skeksis from "The Dark Crystal." Later, their characters appear in a screen test for the original 1982 film.

Unconventional materials from a junkyard are used to create scrap-fantasy creatures that are trapped inside a hanging cage.

A humor-filled challenge requires the designers to create mounted creature heads that magically come to life under the spell of a wizard played by Donald Faison.

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

The designers make camouflaged creatures hiding in plain sight for a mystical swamp-theme challenge. Neville Page ("Face Off") serves as guest judge.

Gigi brings her "Farscape" costar Rygel to the workshop to offer inspiration when the creature designers are given the task to build original alien species attending an intergalactic press conference. Director Barry Sonnenfeld is the guest judge.

The final three receive help from contestants who were previously eliminated as they face their toughest challenge, which is to design, build and perform a full-body mystical creature, complete with props and special effects, for the chance to win a job at Jim Henson's Creature Shop.
