Cehan Pinheads.
I too favoured Cehan, after all they had THREE intelligent
species:- Pin Head (my favourite), Insectoid & Fishtoid (never
did know how the fishtoid drew that long pistol from its holster
as they only had very small fin/hands.
Maybe a very long tongue ?
)
My brother liked the Verbotos robot (only a bucket of bolts).
