Thumpers

The Thumpers were Toa Hordika Whenua's Toa Tools. They were mutated from Toa Metru Whenua's Earthshock Drills when he was exposed to the Visorak's Hordika Venom. They could be used to summon underground Rahi, charge up his Rhotuka spinner, or dig through rubble. They could also function as a melee weapon.

Example Usage
In Web of Shadows, Whenua used his Thumpers to free Rahaga Norik from the rubble which Vakama Hordika had trapped him under.
