Yakko (Rob Paulsen), Wakko (Jess Harnell), and Dot (Tress MacNeille) Warner will be returning in new episodes of Animaniacs one last time, and the Animaniacs Twitter account has released a new teaser trailer for the third and final season of Hulu's revival series.The teaser trailer begins with Brain (Maurice LaMarche) telling Pinky (Paulsen) not to open the green door, which is labeled as "Animaniacs Season 3." Pinky can't resist and opens the door, revealing a montage of clips with the show's theme song playing in the background. The montage includes the Warner siblings messing with cars at the Warner Bros. Studio, a telephone falling on Pinky and the Brain, and Dot riding a motorcycle. The teaser trailer concludes with Pinky saying "I love it," and that he has no notes to give, which leads to Brain giving a sigh.Hulu's Animaniacs revival premiered on the streaming service in 2020. It focuses on stories starring the Warner siblings and on Pinky and the Brain. In the series, the Warner siblings were cartoon characters created in the 1930s. However, due to how crazy and unpredictable they were, they were locked away in the Warner Bros. Studio water tower, until they escaped decades later. Throughout the revival series, the characters react to the way that the world has changed since they last appeared on television in the 1990s. In the revival, the siblings interact with the studio's CEO Nora Rita Norita (Stephanie Escajeda), who took over from Thaddeus Plotz (Frank Welker) from the original 90s series. The Pinky and the Brain segments focus on two genetically engineered lab mice. While Brain's goal is to take over the world, Pinky is more concerned with having fun, which usually leads to their plans falling apart.A still from AnimaniacsRELATED: 'Animaniacs' Voice Cast Guide (for Both the Original and Revival Series!)The original Animaniacs series aired from 1993 to 1998.
