So, you want to cheat, eh? Well, you've found the right place!
If you have a Glitch Chao, it shows a X over it in your transporter. Pick a random chao, and name it so you can identify it. Put him in school. Leave the Chao Kindergarten and walk in again. You will find a nameless chao, rather than your identified chao. That is the All-E-Rank Glitch Chao, do NOT take him out of class. Now, leave and come back again. You will see your named chao, instead. If it is finished with its lesson, pick him up, and take him to the garden. He will become your glitch chao, so put him down and step on the GBA Link. Your glitch chao will dissapear from the Chao World, but I do not know what happens to the named chao...Do not blame us if you lose him!
