Tread Perilously's Doctor Who month continues with the Fourth Doctor adventure known as "Nightmare of Eden."

The randomiser forces the TARDIS to land on a starliner already in the midst of trouble. It's collided with a small freighter, leaving the two ships in a trans-dimensional tangle. The Doctor quickly volunteers to separate the ships, but his efforts keep getting thwarted by other problems like a squirrely zoologist who is using a dimension compression device for his research, a smuggler trading in the most addictive and deadly drug in the cosmos, and a pair of bumbling excise officers who would love to get promoted by pinning all of the problems on The Doctor.

Erik's disappointment in Chris Chibnall gets yet another airing. Lalla Ward once again proves to be the MVP. Romana's extensive wardrobe leads to an interesting discussion about her lack of an iconic look. The old io9 episode rankings get referenced. Strange performances get celebrated, as does the two-person act of The Doctor and Romana. Erik tries to find all the Douglas Adams additions to the story (as he was script editor at the time) while still trying to give writer Bob Baker his due. The Child Compressor returns and Tread Perilously discovers Waahl's Herring Candy.
