According to Enzo's ebay the infamous Penquin suit is up for online auction:
"Enzo Palumbo " The Meow-Meow" Big Brother 12 Penguin Suit.
I purchased this suit 2 years ago on Ebay and am ready to part with it.
The suit comes with a signed letter from Coordinating Producer Dave Barnett
guaranteeing its authenticity and the shipping label I received from
"Our House Productions" in Studio City , CA.
This is 100% the real deal and 1 of the 2 penguin suits he wore on the show."
