Nothing wrong with amorphous globs. It's actually a sound strategy to entangle veggies into a bunch of conspecs tied together, then share the energy around. You may also want to wait until *.robage is greater than 20, otherwise you may be overriding the birth tie and forming a permanent one.
On a not totally unrelated note, refvar--myvar recognition is not too reliable, and one of the easiest codes to break by mutation. The current method of doing so is to put an arbitrary constant into, say, .out6 (-42 .out6 store) on birth, then using *.in6 *.out6 != to recognize other species.
