Terri, Bindi and Robert Irwin

5 of 14
Bindi is now 12 years old and joins her younger brother, Robert, and mother, Terri, on stage—along with a few friends, of course! "This is a little olive python," Bindi says. "The olive python is the second largest snake in Australia. She's just gorgeous."

The Irwin family still runs the Australia Zoo, which spans 1,500 acres. "We literally live in the middle of the zoo," Bindi says. "It's fantastic. Every day's a new adventure."

Seven-year-old Robert has brought a friend from home, as well. "He's called a Woma," Robert says. "Their Latin name is aspidites ramsayi."
