Very long snake is an 8-cell still life and is the long long version of the snake which can be used as a one time reflector.
Very long snake is the sixtieth most common still life in Achim Flammenkamp's census, being less common than cis-block on long hook but more common than integral with tub.[1] It is also the seventy-second most common object on Adam P. Goucher's Catagolue.[2]
