Scorpion (or curl tie bun) is a 16-bit still life. It appears at generation 4761 of Bunnies, lasting for over 400 generations.


Scorpion is the thirty-ninth most common still life in Achim Flammenkamp's census, being less common than beehive with tail but more common than loop.[1] It is also the forty-sixth most common object on Adam P. Goucher's Catagolue.[2]

Glider synthesis

On April 7, 2007 Dean Hickerson found a 4-glider synthesis of this still life.[3]
