The series started development on 1993, with creators Dan Povenmire and Jeff "Swampy" Marsh spending the following 14-16 years pitching the series to multiple networks, and The Walt Disney Company eventually asking Povenmire and Marsh to provide a pilot for them. After developing a storyboard reel, dubbed over by Povenmire, Phineas and Ferb was greenlight for a 26-episode season on Disney Channel. The series lasted 4 seasons, and eventually ended on June 12, 2015.

The fourth season episode "Tales From the Resistance: Back to the 2nd Dimension" serves as a sequel to the film Phineas and Ferb the Movie: Across the 2nd Dimension, with most of the cast reprising their roles from the film as the alternate universe's counterparts of their regular roles.

Milo Murphy's Law (2016-19)
Milo Murphy experiences life with Murphy's Law, which dictates that everything that can go wrong, will go wrong.

The series was first announced in May 2015, under the name Mikey Murphy's Law, before receiving its final name by February 2016. Its first season aired from October 2016 to December 2017, while its second season aired from January 2019 to May 2019. Most of the crew from Phineas and Ferb, including Povenmire and Marsh, returned for the series. While the series is currently in hiatus and its crew moved on to other projects, Povenmire has indicated a third season could be greenlight if the series receives enough views on Disney+.

The series takes place shortly after the ending of Phineas and Ferb, and features several nods to the series througth its first season, culminating in season 2 crossover episode titled "The Phineas and Ferb Effect". Most of the cast reprised their roles for the episode, aside from Thomas Sangster, who was replaced by David Errigo Jr. due to scheduling conflicts. Following the crossover, Dr. Heinz Doofenshmirtz, Perry the Platypus, Major Monogram, and Carl became promeninet characters for the reminder of the series.

Development on Hamster & Gretel began by 2020, with Povenmire as showrunner, having developed the series' concept during work on Phineas and Ferb the Movie: Candace Against the Universe (2020). Joanna Hausmann was hired as head writer by September 2021. Povenmire modeled Kevin and Gretel's relationship on his relationship with his sister. Kevin and Gretel are from Venuezelan heritage, which was inspired by both Povenmire's wife and Haunsmann being Venezuelan. Unlike previous projects, Marsh was not involved in a creative capacity due to him developing projects of his own througth his own studio.
