Answer 2

Find a friend to play with, Make sure they have a Secret base too! Then once you find someone to play with try finding there secret base go inside and all the way at the back press the A button then select take trainers flag and RUN TO YOUR SECRET BASE AS FAST AS YOU CAN!!!!!!! Make sure the other person can't catch you! When you reach your Secret base go to the very back press the A button! =D

But if the other player takes your flag HURRY AND PUT TRAPS EVERYWHERE AND TRY TO STOP HIM\HER FROM GETTING TO YOUR SECRET BASE then go up to him\ her and quickly press the A button!!!!!! =D
