The thumpers were a pair of jackhammer-like weapons that served as Whenua's Toa tools when he was a Toa Hordika.1, 2, 3, 4 Although Whenua lacked elemental powers as a Toa Hordika, he could use his thumpers to charge his elemental earth Rhotuka spinner, which could significantly increase the strength of its effects.5, 1, 2, 3, 4 In order to do this, Whenua needed to hold up his thumpers, launch a Rhotuka spinner from his back, and mentally will it to hover in place in between his thumpers while they charged the spinner, before releasing it again. It took only a couple of seconds to charge a spinner up significantly.6 The spinners could be used to create anything from walls of earth to major earthquakes.1, 2 Whenua could not charge anything else with his claw clubs other than his own Rhotuka spinners.7, 8 Whenua could also use the thumpers to send a signal through the ground to summon subterranean Rahi from far underground.5, 1, 2, 3, 4
Whenua's earthshock drills mutated into the thumpers when he was mutated into a Toa Hordika. When Keetongu cured Whenua, the thumpers turned back into the earthshock drills.CN
