The child, thought to be between four and five years old, had darted out of her parent's sight near the beach in Greece.
A shocked boat crew were left stunned when they spotted a small child on a unicorn inflatable drifting in the sea.
The girl, who is believed to be aged around four-years-old, was found off the coast of the Greek town of Antirio in the Gulf of Corith.
Her parents grew concerned when they lost sight of their little girl and alerted the authorities on the port, reports the Mirror.
Emergency crews were then able to make contact with a ferry near to her location and urged them to rescue the girl.
