Turtle is an orthogonal c/3 spaceship found by Dean Hickerson in August 1989. It is one of the only non-standard spaceships that also works in the HighLife rule. The domino spark that the turtle produces at its back was essential in the creation of the first sawtooth pattern, sawtooth 1212.

Tagalong

In April 1992, David Bell found an extensible tagalong for the turtle.
