Now you see me...
Taste of freedom
While most escaped zoo animals are found within hours or days, Sunny is amazingly still on the lam. The raccoon-like critter has so far evaded search efforts that included the use of infrared cameras and drones. Trained dog units and volunteers have also combed the streets and parks surrounding the Virginia Zoo, but have not caught sight of the crafty red panda.
Ride or die
Well, sort of. This capybara duo came to be known as Bonnie and Clyde after the pair broke out of High Park Zoo in Toronto, Canada. The fugitive capybaras fled during a transfer on May 24, 2016, and spent more than a month on the run. The furry duo made international headlines (though not for sticking up banks like their namesakes, thankfully), with people even tweeting updates with the hashtag #CapybaraWatch.
Bonnie and Clyde were eventually recaptured in traps set by the Toronto Wildlife Centre. And it seems the pair has now settled into a more domestic routine: High Park Zoo announced in March 2017 that Bonnie and Clyde are now parents to three baby capybaras.
Ken Allen's first brush with freedom occurred on June 13, 1985, when the 250-pound (113 kilograms) orangutan scaled a wall in his enclosure and took a stroll down one of the zoo's public paths. Ken Allen broke free for a second time on July 29, 1985, and amazingly, the escapes didn't end there. In fact, the orangutan got even more creative, and even recruited other apes to help. On Aug. 13, 1985, Ken Allen made his third break for freedom, after finding a crowbar that zookeepers had accidentally left behind in his pen. In a remarkable display of cunning, Ken Allen tossed the crowbar to a fellow orangutan named Vicki, who used it to open up a window and let him out.
The orangutan became one of the most famous animals, and at one point, even had a fan club. Sadly, Ken Allen developed cancer and died in 2000 at the age of 29.
Have you ssss-een me?
After a seven-day search, the deadly cobra was found alive and well in a non-public, off-exhibit area of the Bronx Zoo's Reptile House. Thankfully, the slithery creature had never actually left the building. Rather, zoo staff said the female cobra, who was only months old at the time was hiding in one of the holding areas of the Reptile House — a complex area chock full of pumps, motors and other mechanical systems.
In March 2012, Penguin 337 climbed a rock wall at Tokyo Sea Life Park, slipped through a barbed wire fence and spent 82 days on the lam. And it seemed the penguin enjoyed its taste of freedom; on one occasion, the carefree critter was reportedly spotted splashing around in Tokyo Bay. Zookeepers received multiple tips about the penguin's whereabouts, and it was eventually recaptured safe and sound.
Red panda on the run
After an exhaustive search, Rusty was found in the Adams Morgan neighborhood, nearly 1 mile (1.6 kilometers) away from the zoo.
Flaviu killed four lambs on a nearby farm before he was recaptured and returned to the park. Though the lynx was safe and sound, zoo officials said he was "grumpy," and reported that they were trying to find Flaviu a female companion to lift his mood.
Are you in or out?
But alas, the tiger love story was not meant to be. After a few weeks of living contentedly at the zoo, the wild tiger scaled the enclosure's two-story security wall and reclaimed his freedom. Zoo officials, stunned by the tiger's getaway, were subsequently unable to track down the big cat's whereabouts.
Close to home
In the end, the bobcat did not wander too far, and she was eventually found on zoo grounds, near the facility's birdhouse.
