underground chao

This really happened one time in the garden. At first I didn't believe it,somebody on the internet said it could happen. When you go to the back of the garden where there is an invisible wall go inbetween the invisible wall and a big rock,keep homing attacking using Sonic or Shadow and somehow you will break the invisible wall,float out past the clouds so you are in a blue and black area,turn around and float back towards the chao island,you will see that your chao are swimming( or not if they can't) all you can see are their balls over their heads or shadows or tips of their heads.Leave the garden and leave the chao world to stop this. Or you can do it my way by yanking them out of the ground,like carrots. This is in Sonic Adventure 2 Battle. Please comment.
