Eloise LaBelle is a six-year-old girl with a wild imagination best known from Kay Thompson's books, Eloise at the Plaza and more and has a couple of movies based on the books and even an animated series from 2006. Eloise is often unsupervised and spreading fun all around her, much to the dismay of the hotel staff, except for Bill who has no problem with her whatsoever. She has so far only appeared in Christmastime at the Plaza, a project made by PerkyGoth14.
- Eloise first appears in Christmastime at the Plaza.
- Eloise has a crush on Atticus's son, Akito Fudo, and he likes her back. They even share a kiss together, despite being young children.
- According to the story, her family name is LaBelle, and has an older sister named Giselle LaBelle, who goes to boarding school in London and her mother is named Sofia LaBelle who goes to Europe.
