Before the Toa of Ice could respond, Onewa  had grabbed him by the arm and jumped off the ledge.  His powerful legs propelled them well over the chasm, but no where near far enough to reach the other Toa.  It looked as if the stone rats were about to receive two unexpected gifts.

Onewa did not look at all worried.  As the two Toa reached the apex of their leap, he used his Toa power on the ground far below.   An instant later, a pillar of stone shot up midway across the span and directly in the path of the Toa of Stone.
