Universal Studios Hollywood ejected a character dressed as Buddy the Unicorn from its Halloween Horror Nights event. The incident occurred in the park's parking lot, where the mascot was seen interacting with guests and posing for photos before park staff intervened. The character was removed from the premises.

The mascot is from the new horror film of the same name, created by Casper Kelly, known for the Adult Swim segment "Too Many Cooks." The movie features a Barney-like children's television show character whose costume conceals a sinister entity. Despite a modest budget, the film has reportedly surpassed its projected box office earnings, aligning with a broader trend of successful low-budget horror releases attracting audiences over major blockbusters.

Universal Studios' Halloween Horror Nights features attractions based on popular horror franchises, including "Hellraiser," "Sinister," "Stranger Things," and "Killer Klowns From Outer Space." The park has also incorporated additional characters, such as Art the Clown from "Terrifier" and "Freaky" Nikki from "Obsession," as roaming scare actors. The event has expanded its season and includes a year-round attraction in Las Vegas. The park's policy generally prohibits guests from wearing costumes to avoid confusion with park staff, particularly those in elaborate or gory attire.
