When does The Replacements return?

The Replacements is an American animated television series that aired on Disney Channel from July 28, 2006, to March 30, 2009. 52 episodes were produced. The series follows two siblings, Todd and Riley, as they attempt to better their lives by replacing unwanted people.
Todd and Riley lived in what used to be an orphanage with their birth parents' fate unrevealed. While cleaning the floors, they stumbled across a Fleemco comic book containing an ad for the phone. In the process they got new parents: a British secret agent named Agent K and professional daredevil named Dick Daring.
