That.
Also, for certain bones, if you want to rotate something around the z-axis, sometimes Brawl Box will animate the bone on all three axes.
This is natural. Especially for Zelda, I've realized.
Is it animating it oddly, or are you just bothered by the fact that it's animating all three?
No, it's not only animating all 3 axises it's...
Go make a custom animation, then resize the whole leg..Then try moving her foot on one axis.
