Basically, 2;0 is instantly moved to 3;0 by 2;1, where it creates E:3;0 every P:3;0. This E:3;0 is moved instantly by 3;1 to about 1;0. E:3;0 falls down at least one tile into 1;1, and is destroyed either by tile 1;1 or 0;1 regenerating each D:0;1. E:3;0 appears over either 1;0 or 1;1 and creates D:1;x copies of E:1;x upon destruction.
