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.
