This Human miner was among the crowd Harry Mudd was selling his love potion to.
Skeptical, this miner wondered how much the potion would cost, only to scoff at the price Mudd offered it for, three hundred credits. This miner then told James Kirk and Spock to keep out of their business dealings with Mudd, after the two Starfleet officers attempted to arrest Mudd during his sales pitch. He then promptly told Mudd that they had a deal and that he would purchase the potion from him, but quickly became angered when Spock revealed to him that Mudd was tricking them.
This female Ursinoid miner held back the angered male Ursinoid as he lunged towards Harry Mudd, after Mudd's implied comment about his race being repugnant. She later demanded proof from Mudd to support his claims regarding the love potion. (TAS: "Mudd's Passion")
This male Ursinoid miner was angered when Harry Mudd made the generalized statement about the miners of Motherlode as being either "young, old, fat, ugly, or repugnant," a statement on which Mudd quickly backpedaled, stating that it was "nothing personal". (TAS: "Mudd's Passion")
