Film maker Pei Yan Heng was at the beach in Cyrene Reef, Singapore in 2013 when he stumbled upon an octopus stranded far above the water line. Pei filled up a cup of water and scooped up the octopus before releasing him back into the sea. After taking a moment to recover, the octopus went to his rescuer's shoe and hugged it with his tentacle in a sincere thank you gesture.
