Why is Lloyd the green ninja?

Lloyd is the green Ninga because sensi wu read him a bedtime so the story made him grow so he just became the green and I also saw him on the epic battle dragon, that is the new set tht comes out in August of 2012. It said on the box Lloyd zx. That is all I need to say, but if u don't believe me then just find out who the green Ninga is on 3/21/12 at 8pm on cartoonetwork channel 296 if u have direc tv welcome by by
