The Cat Appearances
In Knuckles' Pumpkin Hill stage, go to the one of the train gates. You
can see Big The Cat hiding behind the gate, waving to you. In the City
Escape stage, Big The Cat appears after the last corner in the G.U.N.
truck vs. Sonic scene. Look for him at the right of the screen, running
downhill on the sidewalk away from the truck. In the Tails stage where
you are running from the police and you first get your hover ability,
Big The Cat can be seen again. There is a part in the level where you
need to knock a column over in order to use it as a step to reach a higher
level, from which you hover over to a platform with a police barricade
and two robots. If you miss the platform and fall in the hole, you will
see Big the Cat sitting on the girders underneath the platform. You can
also see him in the battle against Sonic while playing as Shadow.
Bonus Stage
To get a 3D version of the Green Hills Zone stage, from Sonic The Hedgehog,
you must get all the Emblems, including Kart, Timed Boss, and the emblems
for all "A" rating. Once you have them all, which should total
180, the island next to the Green Forest stage will have the face of Sonic
on it.

Get The Gold, Silver And Black Chaos From Sonic Adventure

in Sonic Adventure 2 is located. Put it into Chao Adventure. Load Sonic
Adventure 2 and go to a Chao Garden. Go to the transporter. On the VMU
with Chao Adventure, there should be an egg. It is the egg for your Chao
from Sonic Adventure. When it hatches, it will be back to its first form.
The only thing transferred is the name, but the Gold Chao will be gold,
the Silver Chao will be silver, and the Black Chao will be black.
Note: If you pet or try to influence the Chao you imported, it will lose
it original colors.

Pumpkin Head For Chao
Find one of the Skeleton Dogs; the easiest place to do so is the Pumpkin
Hill stage with Knuckles, and combine it with your Chao. With either Knuckles
or Rouge, start digging around in the Chao Garden. Eventually a pumpkin
will appear. If you give it to the Chao mixed with the Skeleton Dog it
will put it on its head. If you want to take it off, either throw or hit
your Chao.
Quickly Complete Security Hall Stage
In the Security Hall stage you play as Rouge The Bat and are given 5 minutes
to complete it. This can be quite difficult. If you have enough lives
you can do this trick. If you cannot seem to find the Emeralds, intentionally
die. You will keep the existing Emeralds that you have collected. You
will begin at the start of the level and the Emeralds will move to different
places. This is the fastest method for completing the stage if you are
having trouble.
Run On Foot In City Escape Stage
At the start of the City Escape stage, instead of landing on the ground
with the board, scrape the roads on the board. When on foot run full speed
at a wall and get knocked down. Pause the game if you fall after hitting
the wall. Choose to restart the stage to run on foot and not on the board.
Wake A Sleeping Chao
To wake a sleeping Chao, stand next to it and whistle. You do not have
to anger them by picking them up during a nap.
