When Thor and the Guardians of the Galaxy help save a planet at the start of the film, Thor is given a pair of goats as a gift. They end up joining his team and even help pull his ship to get to Omnipotence City. According to the Marvel Fandom guide, in the comics, Thor actually does own two goats named Toothgnasher and Toothgrinder, who help pull his chariot.
Director Taika Waititi told Insider that originally the goats weren't going to scream, but then he was inspired by a Taylor Swift meme. "The goats were always going to be in there because they are in the comics, but we didn't know how they would sound," he explained to the outlet. "Then someone in post-production found this meme of a Taylor Swift song that has screaming goats in it. I didn't even know that existed."
"A lot of people think it's me screaming," he told Insider. "It's not."
The meme in question is from 2012, when someone spliced screaming goats into Swift's "I Knew You Were Trouble When You Walked In."
