In another Wreck-It Ralph 2 scene that was shown, Yesss brings Ralph and Vanellope to the site OhMyDisney.com where they see a crowd gathering by a door guarded by stormtroopers, and the crowd is there to see the Disney Princesses. Ralph and Yesss warn Vanellope not to bother them, but still she manages to break into the guarded room anyway. The princesses, which include Moana, immediately grab their weapons to defend themselves against Vanellope, but she tells them she's a princess too. They interrogate her (has she been "kidnapped or enslaved?") until finally they find common ground with the fact that people mistakenly think their problems are always solved by a big strong man.
The scene ends with Vanellope teaching the women how to dress more casually, with Ariel exuberant as she gets to wear a... "what is it called? Shirt!" Merida also chimes in with her heavy Scottish accent, but nobody seems to understand her ("She's from the other studio.").
The panel ended with the reveal that the filmmakers managed to round up all the original voices of those princesses for the scene. And out onto the stage walked Auli‘i Cravalho (Moana), Kristen Bell (Anna in Frozen), Kelly MacDonald (Merida in Brave), Mandy Moore (Rapunzel in Tangled), Anika Noni Rose (Tiana in The Princess and the Frog), Irene Bedard (Pocahontas), Linda Larkin (Jasmine in Aladdin), Paige O’Hara (Belle in Beauty and the Beast), and Jodi Benson (Ariel in The Little Mermaid) for "the largest gathering of Disney Princesses in history."
