Music Catch 2

i didn't get why this game got a challenge for axe it doesnt have anything to do about sports or anything like that

Aw, hell, it makes you sweat (broken image removed)

I can't do the always purple cheat, is it just me or it doesn't work anymore?

What does this mean?

Earn 10 points when you end with 50+ combos in "Leaves in the Wind" and another 10 points when you complete the Axe "Double Pits to Chesty" move at the end of the challenge! (broken image removed)

Double Pits to Chesty move? What's that? And how do you do that on MC2?

Edit: It's at the end of the challenge when you complete it another screen shows in your achievements screen where you have to click 1-2-3 on a stickman's body.
