Remember No. 337, the intrepid penguin that escaped from the Tokyo Sea Life Park a couple of months ago? It has been spotted in Tokyo Bay looking none the worse for wear:
A Sea Life Park official identified it as the escapee, recognising a distinctive ring round a flipper.
"It looks like it's been living quite happily," Kazuhiro Sakamoto said.
"It didn't look like it has got thinner over the last two months - or been without food," he added.
