Stepbrothers Phineas and Ferb, their older sister Candace, Perry the Platypus, and the whole gang are reunited in Phineas and Ferb The Movie: Candace Against the Universe, coming to Disney+ later this month.

Disney released a trailer for the animated film, which is based on the Disney Channel series that aired from 2008-2015. The movie follows Phineas and Ferb as they journey across the galaxy to rescue Candace, who gets abducted by aliens only to find utopia in a far-off planet, free of pesky little brothers.
