The network included a photo of the beloved animated character in a recent tweet celebrating Pride Month.
“Celebrating #Pride with the LGBTQ+ community and their allies this month and every month,” the tweet reads.
#SpongeBobIsGay started trending as many decided the tweet was confirmation of the character’s sexuality.
Due in part to his close relationship with best friend Patrick Starfish, the internet had long ago decided that SpongeBob was indeed gay.
But the show’s creator, Stephen Hillenburg, dismissed speculation about the characters’ relationship and sexuality in 2005.
Hillenburg died in 2018 at the age of 57 due to complications resulting from amyotrophic lateral sclerosis, more commonly known as ALS.
CNN has reached out to Nickelodeon for comment.
