"Why does everybody think my contracting firm has something to do with sex work?... They think I'm selling Mountain Dew or that I'm fucking people. I really don't understand... I mount things, and I do things." -The Mounting Doer
The Mounting Doer is a Snack-Keeper who was interviewed on Diet Coke & Lilith's House of Snax during Episode #100, "THE DEW SPECIAL." She lives in a fifty-gallon drum of Mountain Dew which she occasionally sips from. She is a self-proclaimed dominant personality and sexually-voluptuous brain, and her profession is to mount things (not people) and do things (handiwork). She can build decks professionally but is unfamiliar with the process of certification or building codes because the last ten presidents in the Snack Dimension have been libertarians.
She never needs to leave her tank because she has the ability to psychically control things from within it, which is why it is so easy for her to be the Mounting Doer. These psychic powers are strong enough that she was able to make Diet Coke levitate during the episode. However, it is impossible for her to use her psychic powers on herself, so her tank needs to be pushed by someone else when she wants to be moved to a new location.
She is related to Snack-Keeper III, but because of how Snack-Keeper biology works, it is unclear whether she is their sister or aunt. Lilith referred to Snack-Keeper III as the Mounting Doer's "brother nephew," and she responded, "That's right."
When she had nothing else to say during the interview, she said goodbye, shut her eyes, and put a blanket over her tank, remaining in the House of Snax quietly for the rest of the episode.
