P36 toad hassler is a period-36 oscillator found by Robert Wainwright in June 1984,[1] being the first period 36 oscillator to be found.[note 1] It is composed of two snackers hassling a toad. The form to the right is a toadflipper and has the smallest bounding box of the snacker-based period 36 toad hasslers. Toadsuckers are also possible, as shown below.

  1. A nontrivial period-36 oscillator, such as middleweight emulator on snacker, could have been constructed from two oscillators of lower period (such as p4 and p9), both of which were known by an earlier date. However, no such LCM oscillators were attested prior to the discovery of this oscillator in 1984.
