The world can be a scary place when you' re young. It can be even scarier when you' re a young little blue penguin(企鹅) , the tiniest of the penguin species. Luckily, there are some humans willing to help. They stepped in to protect Billy, a blue penguin that appeared on a beach in Christchurch, New Zealand.

Spotted on November 29 at the slipway at Moncks Bay, near Sumner，in Christchurch，the little penguin immediately attracted a small crowd. Jeff Mein Smith saw the crowd while he was bicycling that afternoon, and he biked home to get his camera. When he returned to the scene，he found that the penguin had received a little sign, one that read “Hi, I'm waiting for my mum to come back. DOC(Department of Conservation) knows I'm here. Please leave me alone. Keep your dog away. Thanks, Billy the baby blue penguin.”

Billy didn't move away from the sign. The DOC arrived later that afternoon to pick up Billy, though they were surprised to see it on the beach. “It's unusual for a blue penguin to be out in the open on the beach during the day, ”Anita Spencer, a DOC senior ranger, told Stuff.

Billy was taken to the Christchurch Penguin Rehabilitation Center after being retrieved from the beach. Volunteers believe the bird may actually be a female penguin, and is around 2 months old. The chick weighs a mere 550 grams, less than a standard basketball. A blue penguin should weigh around 900 grams at this age. Most little penguins grow up to weigh 1 kilogram.

The center will help the little penguin gain some weight by feeding it fish juice, before it's set free into the ocean.
