Hints

Fast Knuckles 2

How to make knuckles go fast is too turn him into super knuckles then get a speed box and u will go faster then lightning (if you dont know how to get super knuckles you have to get all the choas emralds with rouge and sonic you have to get all his levels done in less then 3 minutes and get all Acs with knuckles then when you get all of knuckles levels done with Acs play as that other echidna girl from sonic adventure 1 in kart race mode and beat it all 3 of them in less than 1 minute) take my advice dont really try this its just to make knuckles go faster instead of sieng knuckles go faster do the sonic thing by going faster.


Invisible Board!

During play on sonics level Metel Harbor, press the Y (green) button on controller 2, Sonic will appear to be riding a board. Note: when this happens, get hit by an enemy to get out of the board.


Upgrades!!!

Search real hard on every level for ALL OF THE UPGRADES. Some need the SONG.


Super Rare Chao

Ghost Chao ~

Give your Chao a Skeleton Dog then some Half Fish (this will give it a flame dot). After, give your Chao some Bats to make it's legs dissapear and then give your Chao a skull or pumpkin hat. It will then put on the hat and you will have a Ghost Chao. (It is best if you make this Chao Dark)

Evil Bunny Footed Chao ~

Make a Dark Chao. Give some Rabbit's to it, then some Skeleton Dogs until it is left with only Rabbit legs. (This may not work first time as the Skeleton Dogs may take away the legs) Once it has only Rabbit legs, give it a skull hat and it will be an Evil Bunny Footed Chao.

Cockroach Chao ~

Get a Black Chao, (either one from the Black Market or a Dark Chao) and give it some Dragons. After, give it some Skeleton Dogs until just the anttena of the Dragon are left on the Chao.

Mystic Chao ~

Download a Jewel Chao from the SA2 Homepage (Looks best with the Green Emerald Chao). Then, give the Chao some Dragons. Once you have done that, give it Skeleton Dogs so it leaves only the Dragons horns and it's tail (That can be very tricky and may require a few attempts). 

Halloween Chao ~

Make a White/Hero Chao and give it a Skeleton Dog. Then give it Bats to make its legs disappear and lastly, give it a Pumpkin Hat.

Double Speed

Ok first get in 2 player mode with a stage that has a run powerup, lets choose radical highway. Ok go through the stage as normal and be sure to have 20 rings (Speed Up) when you see a run powerup-1 is at the beginning at the stage stage where the first chao box is suppose to be in 1P mode.ok use you speed up near the run powerup and sonic will say "Speed Up!" Now get the run powerup fast as you can.And when you have it you will be like 3x faster than normal speed. Try it with Shadow its funny!Even if u press restart this will remain. So this is a good cheat to beat your opponent!

Big the cat also can be seen in Shadow's highway level (forgot the name) right after u get on one of those rocket things you'll see a blimp that says "Got Ring?" as you're falling from being on the rocket you'll see him sitting on the blimp's fin thing. He also makes an appearence in the highway level for tails. It hard mode only though I think. Its right at the end a bridge will fall on you from above (not the one right before the big ring/goal thing) after it falls look up you can clearly see Big the Cat (or Fat in this case I guess he stepped on it and it couldn't take it). Ok one more time that ive noticed. This one is in the level for knuckles/rouge were u get the keys to open the door thing. In that level some were is a metal center thing with gizmos and duhickeys rotaiting around and stuff. If u look at it you can see Big in there in the middle.


Unlock Metal Shadow
