I assume you are talking about Cadhok and Gadhok. Maybe the best Bionicle set ever made. More technic than Bionicle as we know it now, though.
Biggest piece count before those useless playsets, and at the time an excellent source of relatively hard to get useful parts like white teeth, claws, and most importantly, click rotation hinges - the best joint ever made for supporting heavy mecha limbs - no less than 12 of them!

Tell me, who would rather not have this than 6 clones of the same Toa. Apparently - they did not sell well enough though to justify similar big sets in followup years after 2001.
Apparantly, a lot of people thought the Bahrag looked like Bionicle chickens. :-|
