• Big the Cat Appearances

There are several places in SA2 that you can see Big the Cat from Sonic Adventure. Here are a few of them:

2. Radical Highway: After going in one of the rockets look at the blimp to the left and he will be sitting on it.

3. Pumpkin Hill: Go to the area where the train is stuck (it's going back and forth) and he is behind one of the gates waving to you.

4. Cannon's Core: With Rouge, go to the top of the highest pillar in the main room and look up. He's jumping up and down.

5. When you're battling against Shadow with Sonic in the Green Forest area there is a grate. Look down in the grate and you can see Big fishing. | [Sent by inter_a]

After 6 or 7 throws, the balled up S.W.A.T. BOT should blow up and die. | [Sent by JordanPhillips]

• Pumpkin head for Chao

Find one of the Skeleton Dogs; the easiest place to do so is Pumpkin Hill as Knuckles, and combine it with your Chao. As 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.

You can find pumpkins in the regular and Hero Gardens, and skulls in the dark Garden. Get them by digging as Knuckles or Rouge.

• Run on foot

At the start of the City Escape level, 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 game play if you fall after hitting the wall. Choose to restart the level to run on foot and not on the board.

On the green forest level (Sonic), near the end there are three wooden crates (the ones near the green-swamp-creature for your chao). Break them and one is on top of another box. But bounce the one in the ground and you will go to a shortcut. It's easier than the regular path. | [Sent by Travis]

There, you may see a floor made of 4 metal boxes. Bounce on the boxes until you fall through. There, you can have the magic gloves. They don't really come to any good use because there is a risk involved changing your Icon to magic gloves being at a certain distance from the enemy--but it sure is fun! | [Sent by Thomas]

• Tip: Planting Seeds in the Chao Garden

If you play through the Chao Adventure 2, the VMU game, you will find seeds at the end of some of the quests. These seeds can be taken to the Chao garden and produce rare fruits. In order to plant these seeds, you need to first win the shovel and watering can in the beginner Chao races. As soon as you have won these, take the seed out of the VMU and give it to one of your Chao. The Chao will take it, plant it, do a little dance and a little weed you appear. Eventually, it will grow into a tree that you can use to help improve your Chao stats. | [Sent by inter_a]
