By the fourth film in the series, released in 1988, the formula had settled: teenager falls asleep, Freddy improvises a death around whatever’s in the room. For Debbie Stevens (Brooke Theiss), the room has a weight bench and, later, a box of Roach Motel poison. The effects work for the film was split across several shops to make the schedule — Steve Johnson’s XFX handled the waterbed death and the “Chest of Souls” finale, Kevin Yagher did Freddy’s makeup — and George’s shop, S.M.G. Inc., was given exactly one sequence to own: Debbie, start to finish.

The transformation, stage by stage
It happens in three visible stages. First the arms: Debbie is bench-pressing when Freddy leans in as her spotter and drives the bar down. Her elbows bend the wrong way and split open as insect limbs push through the tears.
Then the skin: running from Freddy, Debbie’s human surface starts sloughing away to show a shiny black exoskeleton underneath, and when she goes face-first into adhesive she peels her own face away like a mask, revealing the cockroach beneath. Then comes the scale change: Debbie ends up trapped inside a giant Roach Motel box as a full creature puppet, and Freddy crushes it in his hand.
George remembered Theiss volunteering to perform inside the roach suit and handling the full-body cast and slime without complaint. 1 No source documents the mechanics of each stage; the description above is what the film shows.
The Dream Master pushes the series toward one-liners and music-video pacing. The roach sequence stays on Debbie’s body through all three stages.
