Well here goes:
Thornax turns people crazy/evil/strong when eaten, also addictive.
At the annual fight thing Tuma starts busting the place up and there is fighting.
Some of the dudes turn bad so the villiages train more Glatorians for themselves.
Massive fighting good.vs.evil.
Then suddenly a comet hits the arena.
Comet turns into Toa Mata Iggy Nui!
Fight over with help of Mat
More training, story, plot shock.
Big fighting.
Then all the goodies go to a Great Being and ask him stuff.
Mat leaves the planet.
Then shows Makuta on the those big bananas in the map.
And that is 2009, I think... I'm must be right on a few things.
