From the Bongo panel at SDCC:
"The Simpsons Treehouse of Horror #20 will include a parody of Plants vs. Zombies, where we learn what happened to all of those salads Homer hid at the power plant so that Marge would think he was eating them for lunch. Zombie Apu and his family add an interesting wrinkle to the story…and zombienado will be awesome."
"Zombienado" written by J. Torres with art by Hilary Barta.
