As the evil antagonist in 1989's "The Little Mermaid," Ursula the octopus is a terrifying character all by herself.

That terror rose to an entirely new level on Sunday when a headless animatronic Ursula still performed in character at the Little Mermaid ride at Disney California Adventure.

On Twitter, @dizzzymissy was among a few who posted video of Ursula, as a child could be heard saying "it's broken" in the background."

This happened today which caught me off guard because Disney is usually so critical over things like this #offwithherhead ! pic.twitter.com/biGGYG6ec2— M Lilah (@dizzzymissy) January 28, 2018

According to the Huffington Post, the person who shot that video — who wished to remain unnamed — said children there were visibly upset.

"Immediately after we got off we were ushered out along with everyone else, and the employees looked very concerned," she told Huffington Post. "Many people had seen Ursula decapitated, including kids who understandably were upset."

"It was a pretty freaky thing to see."

It may not have been a joke to children who may have been traumatized, but it provided quite a bit of humor on social media.

Ursula's headless performance was not the only mishap at a Disney park. On Sunday, a similar fate befell an auctioneer at the Pirates of the Caribbean exhibit at Disneyland Paris Park

The infamous Auctioneer at Pirates of the Caribbean literally lost his head I'm curious how long it takes them to fix it #dlplive pic.twitter.com/TZ6JOW64m5— Julian (@HOPAJUL) January 28, 2018

This is what folks at the Little Mermaid attraction would have seen had Ursula kept her head on straight.
