Cha cha is a period 2 muttering moat oscillator, the long extension of clock.

Commonness

Main article: List of common oscillators

As of February 2022, this is one of eighteen 16-cell oscillators which are yet to arise naturally from an asymmetric soup on Catagolue.

It first appeared naturally on July 11, 2022. While the original soup was symmetric, the formation and survival of the object don't rely on the other symmetrical half of the soup. Therefore, this oscillator can be considered natural, given that the asymmetric part of the soup still allows it to appear.

Glider synthesis

All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
