Snacker is a period-9 oscillator consisting of a pentadecathlon hassled by four eater 1s, found by Mark Niemiec in 1972.[1]

The snacker produces domino sparks, but they are rather inaccessible due to the eaters. By putting more pentadecathlons, the snacker is extensible as shown below, whose spark is more accessible. This leads to the first period-18 oscillator, 117P18. A more accessible domino spark can also be obtained using a different oscillator shown below.

This oscillator first appeared semi-naturally in the form stabilized by fourteeners instead of eater 1s in March 2016.[2]

Additional pentadecathlons can be added to extend snacker. The alternate stabilization on the right was found by Dean Hickerson in April 1998. View animated image.

A much more accessible p9 domino sparker that is
only 10 cells larger, and its double variant.
