Frying can sometimes produce "ninja" Harry, dressed in black.
Pressing the button makes him drop from trees. There's only one
screen however.
Use the stock Atari joystick, climb to the top of a ladder and pound
straight down on the joystick (I usually slap down flat down like I'm
trying to "impale" my palm.) Harry will jump straight up...and fall
back down. Nothing useful, just interesting.
