A bittersweet news awaits all "Adventure Time" fans around the world. Cartoon Network just announced that the hit animated series would soon come to an end.

On Sept. 29, Thursday, Cartoon Network announced that "Adventure Time" would conclude in 2018, after the airing of its ninth season. Season 9 is widely expected to include several mini-series and special episodes, which will all air sooner or later in 2018.

Created by Pendleton Ward, "Adventure Time" follows the one of a kind adventures of Finn the Human and his best friend, Jake the Dog. The latter has enchanted powers to change its shape and to change size voluntarily. The series premiered on April 5, 2010, and has attracted a lot of viewers since.

"'Adventure Time' was a passion project for the people on the crew who poured their heart into the art and stories," creator Pendleton Ward said in a statement obtained by  Cartoon Brew. "We tried to put into every episode something genuine and telling from our lives and make a show that was personal to us and that had jokes, too! I'm really happy that it connected with an audience for so long. It's a special thing, I think."

The ninth and final season of "Adventure Time," which is currently in production, is expected to have a total of 142-episode. While many are disheartened by the news, it will definitely be intriguing to see how Finn and Jake's story will be wrapped up.

"'Adventure Time' changed the definition of what a kids' TV series could be, and it's had a resounding impact on popular culture around the world," said Rob Sorcher, chief content officer for Cartoon Network in a press release. "Cartoon Network Studios is proud to have brought together this group of brilliant artists and animators who helped make Adventure Time one of the most critically acclaimed TV series of a generation."
