Simplified: The Great Plains Zoo welcomed six new animals, including five meerkats and a 2-year-old giraffe named Mario. Mario's arrival this week comes about four months after the death of Chioke, a reticulated giraffe who came to the zoo back in 2007 as just a one-year-old. The Great Plains Zoo is also home to another reticulated giraffe, 17-year-old Olivia Dee.
