Piglet the penguin is recovering after being kidnapped from her home then abandoned in an overgrown garden.
The rare penguin was snatched on Sunday night after thieves climbed over a two metre fence to reach her enclosure.
On Monday she was found by locals who heard her donkey-like cries and called staff at Scarborough Sea Life Centre.
Centre manager Ian Hawkins said her abduction appeared to be a cruel prank: "There are some sick, sick people out there, I'm afraid."
