AS YOU PLAY ALONG IN SONIC ADVENTURE 2. YOU WILL FIND LITTLE TUBES WHICH ARE CALLED CHAO DRIVES. YOU CAN GET CHAO DRIVES BY DEFEATING DIFFERENT KINDS OF MONSTERS. THESE CHAO DRIVES ADD TO YOUR CHAO'S STATS. THEY CAN ALSO CHANGE YOUR CHAO'S COLOUR(ONLY IF YOU COMPLETE A RECIPE FIRST. SEE THE RECIPE PAGE)

THERE ARE 4 KINDS OF CHAO DRIVES. THEY EACH ADD STAT POINTS TO A SPICIFIC STAT.

THIS IS THE YELLOW CHAO DRIVE. IT ADDS TO SWIMMING.

THIS IS THE PURPLE CHAO DRIVE. IT ADDS TO FLYING.

THIS IS THE RED CHAO DRIVE. IT ADDS TO POWER.

THIS IS THE GREEN CHAO DRIVE. IT ADDS TO RUNNING.

THERE IS RUMORS SAYING THAT CHAO DRIVES GIVE 8 OR 7 TO STATS. BUT I HAVE STUDIED IT AND IT DOES ABOUT 1 TO 3 TO STATS.
