This is Joss Whedon's company, the creator of Buffy the Vampire Slayer, Firefly, and Angel. "Mutant Enemy" is named after Joss Whedon's first typewriter he got at 15, as revealed in an interview on disc three of the first season of Buffy. In front of a white piece of display board, we see a paper cutout of an angry-looking monster (animated by Joss Whedon himself) moving from right to left. The text "MUTANT ENEMY INC." is scrawled onto the display board in a "pointy" style, with "MUTANT" in red, "ENEMY" in blue, and "INC." in black.
Low to medium. The "Grr! Argh!" and the appearance of the mutant may scare some viewers, but most will just find it humorous.
