How do you unlock pura and fake crash in crash nitro kart

To unlock Pura = Get 100 boosts in adventure mode with Team Bandicoot

To unlock Fake Crash = Get 100 boosts in adventure mode with Team Cortex
Well i do not know what pura is but if you want to get fake crash go to arcade or time attack ( time attack is better cause you do not have to deal with race) and go to the track OUT OF TIME and drive all the way to the bottom right corner of the map and stay to the left wall and you will see some black rocks one of them has a flower on it, drive over it and you will be in the desert. drive outside of the track towards the finish line and you will see two patches of sand one of them has fake crash there next to a fire talk to him and he will say he lost and was stranded there all of a sudden.
THIS IS THE GAMEBOY ADVANCED VERSION.
