In a Houdini-like move, penguin No. 337, escapes from Tokyo Sea Life Park.
The one-year-old Humboldt penguin managed to scale a 13-foot rock wall and was last seen swimming in the nearby Kyu-Edogawa River.
The now wanted No. 337 is one of 135 Humboldt penguins kept at the aquarium and is described as 24 inches tall, with a blackish back and white chest.
Aquarium officials are asking local residents to help in the search for the loose penguin, “Please contact our aquarium if you spot it, without trying to capture or chase it."
Meanwhile, the search continues for the fearless, feathered, fugitive bird. Officials are hoping they can stop the penguin before it swims out to Tokyo Bay.
