A playful seal at the Cornish Seal Sanctuary in Cornwall was entranced by a girl waving a piece of paper by its tank, constantly chasing and swerving to follow the paper's movement.

The filmer commented: "It kind of happened by accident. My daughter noticed that the seal was trying to interact with other people, so she spent some time playing with it!"

This video was filmed on April 14, 2018.

My daughter is waving a piece of paper in front of a seal in an aquarium. The seal is following the piece of paper wherever my daughter moves it, she could even make the seal turn upside down and spin around!
