Banjo-Kazooie Wiki

The Leg Spring is an ability which Kazooie learns in Grunty Industries. This bird-only variation of the Flap Flip is used the same way: by crouching with Z button (N64) and pressing A button (N64). This move allows Kazooie to jump much higher without Banjo's extra weight, making it not only useful for reaching high-up places, but far away places as well when used along with a Glide.

Jamjars' Rhyme[]

Want this one I think

it greatly increases
your jumping height!
First hold Z button (N64), then
press A button (N64),
bend your legs and be
on your way!
