Cross-eyed Opossum has huge Facebook following

This is "Heidi" the Opossum. She's new to the zoo in Leipzig, Germany. Zookeepers picked her up because -- as you can see -- she's cross-eyed, and likely would not survive in the wild.

The zoo hopes Heidi will be a big hit. Her odd appearance has already earned her a Facebook fan page.

Heidi will be on display until the summer.
