soz i only got this game today but when i know i will put it on here bi bi !

you have to upgrade your jump shoes or whatever... and upgrade them again. then you've got
graffity shoes

first on level 2 (snow level) you start on 2-1 go right and theres a red box, select
phineas (triangluar headed guy obviously) and open the box. Once done, you go home (if you
have the workshop there) or stay on in the world and find a workshop. Once found, select
the stack of stuff (next to perry) and select it, make sure you have the right stuff (i
think there is a metorite needed, i forgot XD) make sure you have the right items, if you
do, it will let you upgrade (in color picture) if its not in color (grey) then you don't
have the right tools, start off with basket ball shoes > (dunno whats the next name for
upgraded shoes) > gravity shoes
Hope this helped!

ah its Basket ball shoes > jump shoes > gravity shoes
