Fans' minds were blown by the revelation, tweeting their surprise and gratitude for the sweet internet fodder.
"This tweet about the various Big Birds of the World is the best thing to happen to me all week," one wrote.
"I'm 52 years old and just followed Big Bird. Nice catching up with an old friend," another responded to the account's tweet.
Others couldn't shake the nightmarish image of Garibaldo.
"Big Bird, I'm sorry, but Garibaldo looks like he sells orphans," one fan joked.
"I am very unnerved by Garibaldo's energy and Big Bird's nervous disclaimer re: same," another wrote.
"I love that Big Bird doesn't try to act like Garibaldo isn't the stuff of nightmares," quipped one more.
The heartwarming thread comes after fans mourned the loss of Caroll Spinney, the original voice of both Big Bird and Oscar the Grouch, after he died in December 2019. He was 85.
The New York Post said the famed puppeteer died at his home in Connecticut after suffering for "some time" from dystonia, a neurological movement disorder, the show said.
"Caroll was an artistic genius whose kind and loving view of the world helped shape and define Sesame Street from its earliest days in 1969 through five decades, and his legacy here at Sesame Workshop and in the cultural firmament will be unending," the show said in a statement.
"His enormous talent and outsized heart were perfectly suited to playing the larger-than-life yellow bird who brought joy to generations of children and countless fans of all ages around the world, and his lovably cantankerous grouch gave us all permission to be cranky once in a while."
Spinney played the two iconic characters on Sesame Street since its debut in 1969 before he announced his retirement in 2018. His chronic health issues forced him to give up puppeteering for Big Bird in 2015, but he continued to provide the voices for both characters.
"Caroll Spinney's contributions to Sesame Street are countless. He not only gave us Big Bird and Oscar the Grouch, he gave so much of himself as well," Sesame Street co-founder Joan Ganz Cooney said in a statement.
"We at Sesame Workshop mourn his passing and feel an immense gratitude for all he has given to Sesame Street and to children around the world."
Big Bird has since been performed by Matt Vogel.
