This move is called Shock Spring Jump. Banjo & Kazooie spawn a Shock Spring Pad beneath them to propel themselves upward. The longer the special button is held, the more height they gain. Slows the duo's descent upon starting up if used in the air. Midair jumps and air dodges are still usable, as the duo are not rendered helpless. In the air, the pad itself acts as a projectile after its use like Spring Jump's spring, which can gimp recoveries; unlike that move, however, a grounded Shock Spring Pad cannot be reused by opponents or the duo.
