im pretty sure two dogs are possible. right now im tweaking one to work with
one wheel, and if that works i can make the requested MP version.
a testrun with the upright technic worked so well it became a new mod.
so here as little teaser:

toribirds



four birds pecking the living daylight out ouf uke and tori.
enjoy.

well, i didnt invent this, so i'll explain it of course.
first test looked like this:

O <-- sphere
* <-- joint
O <-- you know

two spheres connected by a joint, in different heights.
now these spheres get a equal constant thrust,
the upper one up plus the gravitational pull,
the lower one down, keeping this simple thing in balance,
even if flipped.
script example:

env_obj 1
	shape sphere
	pos 1 -0.1 1
	color 0 0 1
	rot 0 0 0
	sides 0.1 0 0
	flag 0
	thrust 1 0 0 0.00401
	material flesh
	mass 0.0001
	visible 1

env_obj 2
	shape sphere
	pos 1 -0.1 0.1
	color 1 0 0
	rot 0 0 0
	sides 0.1 0 0
	thrust 1 0 0 -0.004
	flag 0
	material flesh
	mass 0.0001
	visible 1

env_obj_joint 1 1 2
	pos 1 -0.1 0.1
	axis 0 0 1
	range 0 0
	strength 0
	velocity 0
	visible 0

now make the lower sphere two, increase upper sphere diameter, add a head
and you got a toribird.
