The animal rights group and the Republican vice presidential candidate clashed during the 2008 campaign. Now PETA has posted an online game for the holiday season that lets Internet users pelt the moose-hunting governor -- clad in a bikini and fur coat -- with snowballs, Politico reported.

The site urges users to help "make the holidays safe for animals by fighting back against notorious animal abusers."

PETA President Ingrid Newkirk said she got a call from someone claiming to be from Palin's office and demanding that the game be removed from the Web site, and threatening a lawsuit if it isn't.

Politico published an e-mail exchange between PETA and Palin's office in which the governor's spokesman, Bill McAllister, unsuccessfully tries to find out who may have called the animal group from Palin's office, and eventually saying he's "sorry" -- if someone from Palin's office did indeed call.
