>>53577101) evolved slits in its amplification cone giving it "mouths" in the direction of travel catching passing biometal to be absorbed and silt just passing through the opening and passing past its boomer parts and out the other end.
>>53567412) has had quite a bit of devlopment to make it better at waddling side pumps that suck a close ended tube shortening them or lengthening by releasing the valve deforming the now half merged twin cups with independently pumped cups allowing for more fine adjustments along with a top pump that sucks in water and bio metal particulates for its hydraulics.
3) grows another speaker with a deep bottom and a high peak for its vibration PUSHing it forwards and also resonating on attached to sand grains and gravel to kick up clouds to be catch in indention's along its sides that increase its surface area for feeding.
>>53565994) super structure becomes flaky and layered protecting slightly against its own pulse and magnets grow to guide this pulse to the sides and also for any attracted biometal flakes or plates to be lodged between them allowing for more time to absorb it.
5) changes the direction of its wiggle units outwards in a quick succession a moving nub at the end that would make it roll grew LONGER AND LONGER curving along its shape amplifying this motion allowing it to roll in both directions under its own power and stop in one to travel to new feeding grounds.
>>53565926) is not much to speak of increasing its surface area and ease of retention of caught biometal particulates by becoming concave
7) is a quite strange fellow under its delicate field suspending a cloud of LIVING biometal particulates part of the whole but separated able to be moved, absorb and grow able to move silt and such in a limited area around it and to be shaped into offspring this Protomatter.
