When you go to make a new monster, make it in the shape of sonic and you'll get.... SONIC! He is the (I think) fastest monster in the game and I haven't lost a race with him yet.

In the beginning of the game, when you make your monster's frame, choose the dragon frame and give it a long tail and neck with dinosaur legs (curved) and feet with talons. His arms should be long and straight, also with talons. His head should be sharp and with parrot-like jaws (but not the kind you buy at the store). As soon as you are able to put accessories on your monster, give it black dragon wings, black spikes down its back, two black horns on each side of his head, and scary red eyes. He also has to be all black. As soon as you do all of this, you will have the Red Eyes Black Dragon as your monster.

This code is actually very funny. Once the shop is open near the intermediate courses (across the greenish boardwalk), walk into the shop, and there should be a little pig walking around. Go up to the pig and press the A button. The pig will say, "Oink?" Reply "yes" and you will hear a magical sound. Now whenever you are playing the minigames, there will be pigs involved somehow. (If you ever want to turn this code off, than go back to the pig and reply "no".)

Once you beat the Beginner Course and get a frame, you can go to the Intermediate Course. There is a fork in the road - take the water skip one or something named like that, since that's the easy route. You can keep going to the easy route to beat the course faster, and get new frames, and if you score high enough in the games, new items. But at one time or another, you should take the other route to get farther.

When you create a new monster, don't draw it yourself. Choose questions and rapidly hit A. When you get to the details, don't do anything, just hit finished. You will get a Chance Star. Keep doing this and you will have as many Chance Stars as you want!
