Simpsons to turn into zombies for Halloween special

London, Oct 1 (IANS) American animated sitcom 'The Simpsons' will be transformed from a parody of the average US family to zombies, the flesh-eating corpses, in an upcoming episode for Halloween.

The family of five with yellow skin turns into a deathly grey pallor 'after they are turned into the undead in the annual Halloween episode', reports dailymail.co.uk.

The episode forms part of the annual 'Treehouse of Horror' series, which has been running on "The Simpsons" since 1990.

In the episode, lead characters Homer and Marge Simpson find themselves roaming the streets of Springfield with their three children Bart, Lisa and Maggie looking for humans to eat.
