A rough mining planet where Harry Mudd is found selling a supposed love potion to heavy-world miners in the Animated Series episode Mudd's Passion.
Motherlode is the frontier mining world at the start of the Animated Series episode Mudd's Passion. The Enterprise has been ordered to arrest Harcourt Fenton Mudd for a string of frauds and traces him there.
Mudd is working the miners with a new product, crystals that he says will make anyone adore the person who uses them. He proves it with a beautiful woman who appears to dote on him. Spock shows that she is an illusion created by a reptilian creature, a Rigelian hypnoid, and the miners turn angry.
Kirk and Spock take Mudd into custody to save him from the crowd. Aboard the Enterprise he talks Nurse Chapel into trying the potion on Spock. This time it works, and it soon spreads through the ventilation to the whole crew.
