This cute moment shows five-year-old Oliver playing 'tag' with a penguin at Colchester Zoo in Essex, southeast England on October 25.

“A penguin started to follow my son as he ran alongside the glass. My son stopped a couple of times to see if the penguin was actually following him and the penguin stopped too. This went on for about 5 mins or so,” said his mum Ami, the filmer.

We were at colchester zoo in October 2019 when a penguin started to follow my son as he ran along side the glass. The penguins seem to be playing with him as they stop when he does and continue swimming when he starts running again.

were at colchester zoo in Essex when my son who was 5 at the time started to run along the side of the penguin enclosure. One penguin started to follow him and swim along side him. My son stopped a couple of times to see if the penguin was actually following him or if it was just a fluke and the penguin stopped too. This went on for about 5 mins or so although it probably would have been longer if we hadn’t have had to have moved on to the next enclosure.
