*Ears somewhere; topside is better but not of necessity where ours are; two is better for determining direction, but three or more just creates confusion.
*Locomotion appendages, minimum one; more is better.
*Manipulative appendages, minimum one; more is better.
*A CPU brain - somewhere within.
*Size: Not too large; not too small.
*Genders: At least two to achieve genetic diversity, but not too many least things get too complicated.
*Support structure(s): Both internal and external appear to work, so that might be a tossup."
