I think the Skull Bonkle commercial had a hidden story to it, so I decided to give you my interpretation of it.
SKULL SKELETONS: Do you think we should hep the big skeleton thing that just revived us?
SKULL SKELETONS: No, not really.
SKULL SKELETONS TURN TO DUST AS SKULL GRINDER IS DEFEATED BY TAHU WITH ONE BLOW IN SKULL GRINDER'S WEAK SPOT FOR 999,999,999 DAMAGE!
TOA: Should we help Tahu?
TOA: Nah, we hate him. He's full of himself, let's watch him get defeated and get his comeuppance.
TAHU DEFEATS SKULL GRINDER WITH ONE BLOW IN SKULL GRINDER'S WEAK SPOT FOR 999,999,999 DAMAGE!
TAHU: I am the best Toa in all of existence! Now, I demand you all paint yourselves red and swear total allegiance to me because I'm awesome. We awaken Ekimu this day!
SKULL SCORPIO shows up to the scene of the battle - more accurately, the aftermath.
SKULL SCORPIO: *curses loudly in skeleton language*
SKULL SCORPIO crumbles to dust, since it has only just realised the Skull Skeletons lost the crucial battle against the Toa who seek to awaken the evil spirit of Ekimu.
AND SO, OKOTO SLOWLY SANK INTO THE SEA AS PER EKIMU'S WISHES, REVEALING THE GIANT ROBOT THAT SLEPT UNDERNEATH. THE GIANT DEATH ROBOT, THAT SOUGHT TO DESTROY THE PLANET. GOOD JOB, TOA 'HEROES'.
