When Australian surfers found three weak juvenile penguins on beaches near Sydney, they contacted the Taronga Zoo, which admitted them to their animal hospital. After almost three months of rehab, the still tiny penguins were healthy enough to return to their ocean home. Watch some of their recovery and their release in the touching video below and make sure to catch their post meal singing session around minute 1:40.

Penguins come ashore to molt and during that time they are particularly vulnerable to predators.
