Western Animation - Wreck-It Virgin 2 vs. Spider-Chad: Into the Chadverse

Yes. That is the joke. With the exception of Shrek 2 and Spirited Away, Disney or Pixar had one every best animated feature oscar up to that point, because Disney knows "The Academy" doesn't actually have any respect for animation and just goes with "whatever my kid liked most this year"

There was also Wallace and Gromit: Curse of the Were-Rabbit, Happy Feet, and Rango.
