The clip begins with Mulvaney opening a pink and white pinstriped door to reveal an outfit consisting of flats, a short skirt, puffy button up shirt, and a pink bow, the same clothing worn by the fictional character.

"I am Eloise. I am six," Mulvaney mouths along to the sound of a girl's voice, ushering viewers into the room.

"I'm a city child, I live at the Plaza Hotel which is huge, and wonderful, and tres elegante especially at Christmas time."

While mouthing the words, Mulvaney prances around the room, adorned with Eloise-themed objects, before falling onto a bed, legs up in the air.

"Pretending to be a woman wasn't enough so now he’s pretending to be a little girl?," one Twitter user said. "This isn't normal. This is mental illness."

Another suggested Mulvaney was simply living out a fetish, saying it was "fine," so long as Mulvaney doesn't "inflict it on everyone without consent."

"Let fetish be fetish and keep it in your bedroom and dungeons," she quipped.

Mulvaney, who recently celebrated 365 days of "being a girl," has undergone facial "feminization surgery," but still has male genitalia. Instead of going all the way, Mulvaney has instead encouraged people to "normalize the bulge."

Mulvaney was invited to speak with President Biden at the White House in October, where the self-identified "bimbo" asked the commander in chief about his feelings on medical gender transition for children and teens.

"I feel very, very strongly that that you should have every single solitary right, including, including use of your gender identity bathrooms, but public," Biden said.
