GREEN PORNO, Isabella Rossellini’s quirky short film series about the reproductive habits of animals, has been a web sensation. To celebrate the launch of the latest season and the release of the GREEN PORNO book, we’ll be holding a GREEN PORNO trivia contest this week on Twitter.

All week long we’ll post GREEN PORNO trivia questions. And each day, one GREEN PORNO savvy @SUNfiltered follower will win a signed copy of Isabella Rossellini’s new GREEN PORNO book.

Here’s how to participate:

1. Follow @SUNfiltered on Twitter
2. Be on the lookout for the daily Green Porno trivia question
3. After the daily question is posted, send a tweet beginning with the phrase “Answer @SUNfiltered” followed by your answer and the hashtag #GreenPorno

Each day, one winner will be selected randomly from all the correct
answers. By the end of the week, 5 lucky GREEN PORNO experts will have their own signed copy of Isabella Rossellini’s Green Porno book!

Also check out Bust.com’s giveaway for an extra chance to win!

Every male creature on the planet has a unique “piece of equipment” specifically designed by mother nature to work “hand in glove” with the female of its species.

Are you up to the challenge of matching nature’s creatures with their appropriate “features?”

To take the challenge go to any of the 4 participating blogs below. Find the penis in the photo on any of those blogs, enter the animal’s name in the comment section and get a chance to win an eco-friendly, Sundance Channel gift bag (it’s not just a bag, it’s got stuff in it too).

To help you find the proper penis, we have posted a Green Porno “Grand Gallery of Penises” on Sundancechannel.com. Click through the gallery until you find the penis that matches the photo on any of the blogs below.
