be the first one to hit him 6 times

the first priority is to KEEP UP WITH IT!!! if you lose the robot you screwed it,also as
soon as you have the grind part
take the rail! then just hit him 6 times(for each lap you'll have to hit it twice)

when you use the boost use green platform to catch up

OK, so when you get to the part where there's a rail grind it and then when he makes
everybody do the super boost thing ram into the floating platforms that pop up out of the
ground because they will give you a boost. Then try to ram him before the boost thing
stops. Then do it 2 or 3 more times to beat him.
