The Professor's Lab from outside ("The Book of Doom")
Professor Monkey-for-a-Head's Laboratory is a giant space habitat, and the lair of the galactic evil genius Professor Monkey-for-a-Head. It is also the dwelling place of his numerous failed experiments (except for the Robo Chicken), and where his only genuinely good contraption, the Super Suit, was created.
The interior of the laboratory was used for "Level 5" in the original Earthworm Jim video game.
It was also featured in the animated television series, where the laboratory was seen from the exterior for the first time.
