It began with "Orb", which was watched by 0.71 million viewers (a decrease from the previous-season finale, "Islands Part 8: The Light Cloud", which was seen by one million viewers). The ninth-season finale, "Three Buckets", was watched by 0.85 million (the lowest-rated "Adventure Time" season finale at the time). Critical reception of the season was mainly positive, with the episodes making up "Elements" largely well-received. For her work on the episode "Ketchup", Lindsay Small-Butera won an Emmy Award for Outstanding Individual Achievement in Animation at the 70th Primetime Emmy Awards. Cartoon Network Studios and Frederator Studios produced the season. A set containing the entire season was released on September 4, 2018.
