Knux Upgrades

These are the places where you get Knuckles upgrades. SHOVEL CLAWS: Be Knux (Knuckles) and go to the Mystic Ruins. Go to Tails workshop and go behind it and fall off the cliff there. You will see a cave there and there will be a person there too. Go into the cave and you will see a cart that goes to Chao Garden. go to the left of that and you will see a monkey in a cage and the shovel claws upgrade. GET IT!!!!! Then go to the little hill to the right with Eggmams face popping out of it and dig in to the hill and a button thing will pop out. Grab it and go tothe monkey. You will see the door out is closed so hit the button by the monkey and he will explode and the door opens. Take the Same button and go to Angel Island.(This has nothing to do with getting the upgrade but I like helping you people out.) Just before you go over the bridge there will be a monkey and a closed door to the right. put the button by the monkey and press it.BOOOM!!! go into where the closed door was and you will be in Red mountain. FIGHTING GLOVES: Go to Bigs house and climb the tree. (For those people who don't know where bigs house its in the forest maze. it looks like a little hut.) After you climb the tree go on the cliff there and you will see the Fighting Claws! DA TA DA!!!!

Place Where Speed Shoes Are

First of all You must be Sonic. Then go to Station Square and find a manhole by the shop where you get the gold chao egg. Jump into it. Then you will be in the sewers. In the sewers you will find a raised platform and a little porch like thing popping out from the wall. Jump onto it then go left and there you go! You got the Speed Shoes! Hint: After you get the Shoes keep going forward and a wind (or some thing. I can't remember now) will take You to the shop where you get the gold chao.

Sonic Chao

To get a chao that resembles Sonic, only give it rabbits and food. Soon it will grow spikes, but dont stop feeding it. It will turn into a cacoon and emerge like Sonic!

It will save 15 sec of climbing the mountain {the normal way}.
