Snacker is a period-9 oscillator in which four eater 1s hassle a pentadecathlon, found by Mark Niemiec in 1972.[1][2]

The snacker produces domino sparks, which can be used for a p36 toad hassler. In other cases the sparks are largely inaccessible due to the eaters; however, the snacker can be extended by putting more pentadecathlons as shown below, or an alternative eater which is also used in L200 can be used, and so a more accessible period 9 domino spark can be obtained -- this method was used to create the first period-18 oscillator, 117P18. Stronger domino sparkers are also known, for example 50P9 and 104P9.

This oscillator first appeared semi-naturally in the form stabilized by fourteeners instead of eater 1s in March 2016.[3]

Additional pentadecathlons can be added to extend snacker, as used in 117P18. The alternate stabilization on the right was found by Dean Hickerson in April 1998
