Sometimes you have to get out of your cage. In the case of the chimpanzee Chacha, that meant escaping from the Yagiyama Zoo in Sendai City, Japan and leading authorities on a two-hour-long chase.
Chacha made his way to a residential neighborhood on April 14 and was walking on power and telephone wires, taking in the sights. As authorities closed in, he was none too eager to be returned to the zoo based on his reaction. Officials eventually subdued Chacha with a tranquilizer dart and caught him in a waiting net. Despite his dramatic fall, the 24-year-old chimp survived the experience. (And zoo officials are investigating how he got out in the first place.)
