We hope you're sitting down -- Cartoon Network on Thursday confirmed its hit TV show "Adventure Time" is ending in 2018.
Fans will have to bid Jake the Dog and Finn the Human a hearty farewell, eight years and 71 hours of programming after it began.
The network announced the show's next season will be its last.
"Adventure Time" will continue to debut new episodes on Cartoon Network over the next two years, including specials, miniseries and the ninth and final season.
Fans took to social media to share their grief over the announcement.
Adventure time is ending, Regular Show is Ending, Gumball is ending. I'm running out of reasons to watch Cartoon Network.— Jim Gisriel (@JimmFORCE) September 29, 2016
Happy Adventure Time is getting a proper finale. One of the most creative shows in cartoon history. Any other opinion is wrong.— Backthony Hometano (@theneedledrop) September 29, 2016
