Thalia Halpert-Rodis is one of the students in Bell Valley Middle School and one of the friends of Tommy Frazer in the fifty-ninth Goosebumps book, The Haunted School. She is also one of the members of the missing Class of 1947 who was trapped in the colorless dimension, Grayworld, for 50 years.


The Haunted School

Not much about her is known, including who her parents were, where she lived in Bell Valley prior to being trapped in Grayworld, nor anything else. The only thing is that, like the other twenty-four members of the missing class of 1947, Thalia was one of the kids sent to the colorless classroom by the mysterious and evil photographer Mr. Chameleon for unknown reasons. She was one of the kids who managed to retain their sanity while most of the other kids went insane and started a weird and terrifying cult outside the school due to being without color for so long.

One day she discovered her lipstick, which was buried in her purse for so long still had its red color. Excited by this, she started drawing on the walls with it, and to her shock it made a hole in the wall wherever she spread it. Without thinking, she created a red window, climbed through it, and escaped. However, the hole vanished before she could return for her friends. Despite being back in the modern world, Thalia discovered she was still without color and totally stuck in her gray form. She began covering herself with thick make-up and lipstick. She also began using blue contact lenses to conceal her gray eyes and dyed her hair blonde. This was a constant state and it was because of this, that Thalia was endlessly teased by the other kids. Despite being forced to hide her otherworldly condition, Thalia still helped Tommy and his friend Ben Jackson on the local Dance Decorations Committee, but never forgot about saving her friends so she mostly stayed in the school searching for a way back into Grayworld.

Eventually she returned to Grayworld, via a hidden elevator. However, Thalia decided that because of having to constantly cover herself in make-up and lipstick, and the other kids teasing her; she'll never be a part of the world of color and brightness and chose to remain in Grayworld with her friends though she still offers to help Tommy and Ben escape from there by creating another lipstick window. Her final words to them are "Don't forget me!" before the hole closes up separating both worlds from one another. But when Tommy and Ben made it back to the desk, they discovered Mr. Chameleon was there and he took their class photo, bringing them back to Grayworld.

Goosebumps HorrorTown

The story largely remains the same, with a few notable differences. After escaping to the color world, she hides out in a beauty shop where she gets some makeup to cover some of her gray-ness. In the end, she returns to the color world with the others, as closing up the portal for good brings her color back. Additionally, all of her former classmate had lost their way although she reminds Lucy that they were her friends at one point.

General information

Physical appearance

Thalia is both tall and thin, with long blonde hair and gray eyes. She wears blue contact lenses to hide her gray eyes. Her and Ben are often thought to be siblings because they look alike even tho they're not related at all.

In Goosebumps HorrorTown, Thalia is shown to be all gray, minus her lips. She also wears a bright yellow jacket and blue pants to cover her gray body. She have purple hair and black eyes.


Despite her imprisonment for 50 years and being bullied by the other kids, Thalia is considered to be a very kind person, evidenced by the fact that she attempts to save her friends in Grayworld. She also is friendly to both Tommy and Ben, actually betting that Tommy wouldn't get lost when he went to fetch the red buckets of paint she requests at the beginning of the book, and eventually helps Tommy and Ben escape Grayworld in the end. Despite this, she has a bit of a temper, evident when the main bully Greta steals her lipstick and she nearly goes berserk trying to get it back. She also laughs at most of Ben's lame jokes and appears to be a truthful, honest person as she reveals her true identity to both boys as well as how she escaped.
