Bull snakes are often found in North America, so it was unusual to find one of the slithery creatures outside a pub in south London.
On Tuesday, the reptile was seen relaxing in the shade in front of the Little Crown bar in Deptford.
It was attempting to find shade from the sweltering weather, like the majority of citizens in the city.
