When your health is gone, quickly exit the level then return to it and you should be invincible.

In the second level, Andy's Neighborhood, you can defeat RC without the jet boots. Here is how: Every time the RC car attempts to pass you by, simply stand in front of it and wait for it to collide with you. It will stop for a short time. Keep running along and run into him at all costs. Be sure not to land in the cemnt mixture. You can repeat this process to get the Pizza Planet Coin.

In the first level. In the room Hamm is in. Jump on the chair so you go In the air and land. Instead of jumping over to the next platform just walk off and turn around. You should get his ear.

At the title screen press: X, Circle, Square.

At the title screen press Up 4 times,Down 2 times, Up 2 times, and finally Down 3 times. If the code is done correctly you will unlock all the levels but you still have to complete all the missions because the Pizza Planet Tokens will not be available.

On level one if you get 100 or more coins go talk to Hamm and he will invite you to the secret room called Woodys workshop. Here you can collect extra hints, cheats, and tips in order to beat the other levels (this will make it easier and will show you were everything is at)

In the level Al's Toy Barn, go up to the the rooster and he will ask you to get him the chick that's in the egg at the other side of the level. After you get him the chick, he will ask you to go back for a Pizza Planet token that's in the egg. Get it, then exit the level. Go back in, and go back to the rooster. Talk to him, then get the chick again. Instead of giving it to him, keep it, and it will count as one of the 5 chicks that you have to get for the hen.
