The Hordika teeth were a pair of weapons that served as Nuju's Toa tools when he was a Toa Hordika.2, 3, 4, 5, 6, 7 Although Nuju lacked elemental powers as a Toa Hordika, he could use his Hordika teeth to charge his elemental ice Rhotuka spinner, which could significantly increase the strength of its effects.3, 4, 5 In order to do this, Nuju needed to hold up his Hordika teeth, launch a Rhotuka spinner from his back, and mentally will it to hover in place in between his Hordika teeth while they charged the spinner, before releasing it again. It took only a couple of seconds to charge a spinner up significantly.8 Nuju could not charge anything else with his Hordika teeth other than his own Rhotuka spinners.9, 10 Nuju could also rub the Hordika teeth together to make a signal that summoned flying Rahi.3, 4, 5 He could also use them for climbing.4
Nuju's crystal spikes mutated into the Hordika teeth when he was mutated into a Toa Hordika. When Keetongu cured Nuju, the Hordika teeth turned back into the crystal spikes.CN
