- One half of a lumps of muck is removed and the remaining active region evolves into a dove in 39 generations.
- The dove evolves into the 3-tick descendant of stairstep hexomino in 23 generations, along with a large spark.
The first stage can be done in many ways, such as a middleweight emulator, a single eater 3 (by David Buckingham), or a regenerative loop catalyst. The stabilization using a block, an eater 1 and a clock is the smallest in terms of population, as shown in the infobox.
The second stage requires a quick suppression of the byproduct spark, which appears to be hard. Bill Gosper's original solution is to use the period-4 fountain. In April, 2010, David Buckingham reduced the bounding box with two copies of blocked p4-3, as shown in the infobox. On September 25, 2021, GUYTU6J found a stabilization using Merzenich's p31, reducing the population to 132 but increasing the bounding box. This is currently the only variant with a known glider synthesis.
Dean Hickerson also noted that arbitrarily large agar can be built using many copies of lumps of muck.
