Animaniacs is an American animated comedy musical streaming television series developed by Wellesley Wild and Steven Spielberg for Hulu. A revival of the 1993–98 animated television series of the same name created by Tom Ruegger, the new series sees the return of the Warner siblings, Yakko, Wakko, and Dot (voiced respectively by their original voice actors, Rob Paulsen, Jess Harnell, and Tress MacNeille), and Pinky and the Brain (voiced by their respective original voice actors Paulsen and Maurice LaMarche). The series was first announced in January 2018 with a two-season order and Amblin Television and Warner Bros. Animation producing; the series premiered on Hulu on November 20, 2020. The second season premiered on November 5, 2021. The third and final season was released on February 17, 2023. Premise Animaniacs continues to focus on the adventures of the Warner siblings, Yakko, Wakko, and Dot—three inseparable, irascible kids—as they embark on further adventures after being absent from television for 22 years, bringing with them the usual wackiness and mayhem they create while adapting to the changes and life of the 21st century. Episodes are composed of several shorts, with each episode consisting of segments following the adventures of Yakko, Wakko and Dot; the vast majority of episodes also include a segment featuring fan-favorite characters Pinky and the Brain—two lab mice, one of whom is intelligent and wants to take over the world, while the other is dim-witted and clumsy, often messing up his friend's plans. Recurring segments new to the revival include Starbox and Cindy, which follows a miniature alien who is part of a fleet who want to destroy the Earth that ends up in the hands of a young girl, The Incredible Gnome in People's Mouths, centered on the titular gnome who ventures into different people's mouths to speak for them, Math-terpiece Theater, which involves dramatized math lessons taught by Dot, and Everyday Safety, a parody of 1980's safety videos featuring the Warner siblings.
