How do you get in the ninja class on aqworlds?

to get ninja class all you need to do is go to greenguardwest just by the pet shop

then you are at greenguardwest move forward where the arrow is then you click on the ninja where it shows (!) you click it then go on shop then you will see ninja class if you have enough money though because it is 1,500

NOTE: sometimes it might say requirements not met so try and be on a different level then buy it
