there is an alternate way to ghetto jump that gains just as much height! just hit B twice at the beginning of a jump, and youll hear the sound effect twice, when you do the space (2nd) jump, you will shoot up heigher than normal, resulting in an alternate ghetto. Strangly, you cannot do a screw attack in the same jump, but underwater you can do a gravity boost (kind of strange really)and the best part is, you dont have to be next to a wall to use it! Note: you DO NOT hold L or R when you do this, holding L will do a L-Lock jump or Langle, and R does nothing!
NOTE:this trick needs further testing and a video show that it has much height as ghetto jump.
Note: Tested. This trick does not give any extra height.
