I think it would have been cooler and more interesting, if Bem had broken down into, say, about 20-40 Tribble-sized (

) pieces, which all floated out and reassembled. More interesting, because a) there would have been greater similarity among the pieces, and b) they could have at least mentioned the idea that Pandronians could assemble into a variety of different shapes, including non-humanoid ones, and maybe even demonstrated that. Maybe Spock mentions that species previously thought distinct based on provisional data were possibly both Pandronians in different arrangements.
