Sonic Adventure DX Director's Cut Cheats

Glitches and some Hazards
Glitch 1:
Go to the Egg Carrier Chao Garden and go to the tower thing behind the Chao Transporter (this only works with Sonic). Do you see a few flowers to your left? Walk into them and then you'll go up the tower thing! Cool, heh?

Glitch 2:
I don't know if this is a glitch, but it's cool. Go to the tower thing and run up it. When you're at the top, you'll be sliding down. Slowly at first. When you get to the red part (about half way), this is when the fun starts. You'll be sliding down the tower thing really fast and when you reach the bottom, you'll run for a bit. As far as I know, this only works for Sonic, Tails and Knuckles. Try with the other characters to see if it works for them as well.

And now for the Hazards:
The Chao Gardens are a safe place to be, right? They're not! You can drown in the Egg Carrier Chao Garden and the Mystic Ruins Chao Garden! In the Egg Carrier Chao Garden, go to where the water is deepest (any character except Big or E102 Gamma). You will know if the character has gone in deep enough when there's bubbles coming out of their mouth. After about a minute or two, the drowning music will play. The character will have 10 seconds to get out, but if you don't, then the character will have lots of bubbles coming out of their mouth and then lifelessly resurface. Dead. And to drown in the Mystic Ruins Chao Garden, go as Tails or Amy (I am not sure if this will work with any other characters) and go to where the water is deepest, by the waterfall. After some time, the drowning music will play. If you don't get out of the water within 10 seconds, the character will lose a life.
