Gravity Falls went out with a big bang last week. The series finale of creator Alex Hirsch’s toon drew 2.9 million total viewers on February 15 to become the most-watched program in Disney XD’s history. The net also said the episode titled “Weirdmageddon 3: Take Back the Falls” was the No. 1 regular series telecast ever across multiple demos including kids and boy 2-11 and kids and boys 6-11.

The series about twins Dipper (Jason Ritter) and Mabel (Kristen Schaal) who live with Great Uncle Stan in the off-kilter town of Gravity Falls, OR, accounts for the Disney XD’s top nine regular animated-series telecasts of all time in Kids 6-11 and the top seven in Boys 6-11.

Hirsch said on social media in November that he was ending Gravity Falls, which launched on Disney Channel in June 2012 and moved to Disney XD in August 2014. “This is 100% my choice, and its something I decided on a very long time ago,” he wrote at the time. “I always designed Gravity Falls to be a finite series about one epic summer — a series with a beginning, middle, and end.”

Meanwhile, over on sibling channel Disney Junior, a visit from Frozen‘s snowman boosted Sofia the First to its highest rating in more than a year. “Olaf and the Tale of Miss Nettle,” featuring Josh Gad as Olaf from the Disney megahit feature, ranked as the series’ most watched episode in 15 months in total viewers (3.3 million) – and its No. 5 telecast overall.
