Kanoka toss was a highly dangerous street sport played in Metru Nui. It was a favorite in Ta-Metru and Onu-Metru. Two players competed against each other. One player hurled a Kanoka disk with all of his might, while the other attempted to catch it. The trick was to catch the disk after it had expended so much momentum that doing so would not trigger its power. This required split-second timing and a lot of courage; it was not unusual for Kanoka toss players to wind up frozen, shrunken, or reconstituted into something even a Rahkshi would be sickened by. Onu-Matoran took the game one step further, going down to Archive sub-levels to play "Kanoka toss in the dark."2
