98P25 is an unnamed period-25 oscillator discovered by Noam Elkies in October 2002. In terms of minimum population, it was the smallest known period-25 oscillator until the discovery of an improved form of pre-pulsar shuttle 25.
It works by using four fumaroles and two blocks to hassle two honey farm predecessors. Half of this oscillator can be replaced by a toaster, as shown below.
