How To beat Prototype Of Shadow

To beat the bio-lizard you must be Shadow. Dodge its attacks (shadow ball, bite, ailwhip, and comet attack). Also avoid the water. When it charges up, grind(press A onto a rail) up the rail coming toward the giant orb. When he uses comets use Homing Attack (Press A in mid-air) to go up and hit the orb. Continue till he raises the gravity. When he does, avoid the comets and pull yourself up on his back and attack it with homing attack. He's Defeated, not Dead      You must beat him a second time in space while being Super Sonic and Super Shadow. Press A and B to move and hit the red swelling thingies.

Click the Chao. When it comes out of the machine, it will be golden, at least mine was.  If you try to take any more chao from your game boy, it will not work, it will say there is nothing there.  On your game boy, click the L button on the top left hand side.  The store menu should show up.  You can buy eggs for 0 rings ( which you can't do when you have a chao in the tiny chao garden)!  Get an egg. Connect the gameboy back up to the game cube ( if u unplugged the cord ).  Take the egg. You can do this as many times as you like until you fill up the garden.

If you make it out of the hole, horrayyyyy! You found the Air Necklace.

Infinite Animal

First what you do is get your Chao to sit still by petting it it only lasts for a couple seconds. So hurry. Next get the animal you want to use (might want to put it right next to Chao) stand near the Chao not next to it so it can take the animal from you but near so you can set the animal next to it. Then drop it and repeat. I've tried it and it works he's a lvl. 36 or so swim and he's only a little over 1 year old. It may not work at first but once you get used to it it will work without hassle.

Ghost Chao

To get ghost chao,  go to the black market in the chao kindergarten.  Buy a white egg.  Either wait until it hatches or hatch it yourself.  Then get lots of bats(3 or 4, maybe more, it took me 3) from the levels and give them to the chao that came from the white egg.  Then go to the fortune teller and name him Ghostly.

Pumpkin chao

Get some skeleton dogs(good place to do it is pumpkin hill or pyramid cave).  Give them to your chao.  Then start digging with knuckles ou rouge and eventually a you'll find a pumpkin.  I found my pumpkin in the hero garden.  Give the pumpkin to the chao who you gave the skeleton dogs to and he will put it on his head.

Easy way to beat the Last Stage on Hero and Dark

For both Hero and Dark you must fight the hedgehog that resembles you. You will fight on a long runway that goes on until you win. When you start fighting you can hit the enemy regularly for awhile until eventually he'll block your attack. The best way to hit him then is to wait until they get far ahead of you. You then start up the Spin Dash in the middle of the runway. Eventually the enemy will start their special attack. Right before it hits you release the Spin Dash. If you stay perfectly strait you'll hit him. Do this until your opponent dies.

Beating the Last Boss, Biolizard, the REAL Shadow

There are 2 parts to this battle.  The first part you dodge his attacks(shadow ball, bite, bombing, charge) then when he gets energy from his life force orb, grind up the pipe coming out of his mouth then use the homing attack( pres A in the air) and hit the orb on his back.  Then when he uses the bombing attack that surrounds him,  use the homing attack until you get to the orb and then hit it.  Then when he lifts the gravity,  dodge the bombs and hit the orb and kill him.  When you become SuperSonic and UltimateShadow,  press A and B to attack and hit the swelling spot with the charge attack.  If you run out of rings, you lose.  To switch between Sonic and Shadow, Go under the Finalhazard(the boss) and it will switch between characters.  When you beat it, you warp ARK back into orbit and Shadow gets caught in The explosion of the boss and dies. 

Secret Races (And hard Chao Karate)

When you first go to Chao Race, you only have beginner and multi-player races. You can get more of them! To get the Jewel and Challenge races, beat all 3 levels of all 4 courses.
