Hint :
Green laser locations:
Green lasers will allow enemies to be killed with a single shot. They can be found at the following locations.

Andy's House: When you go to the garage, find a way to get up to the van. When you get to the top, you will see a green laser.

Andy's Neighborhood: Find your way to the location with a broken car. The green laser should be right in front of you.

Alleys and Gullies: Turn to the right when you see the first airplane box.

Battery locations:
Start game play on the Bombs Away level and move all the way to the left to find a battery. Then, move all the way to the right to find another batter.

Getting on the trees:
Begin game play on the Andy's Neighborhood level. Climb on the swing, then reach the other swing. Move to the tire with a rope. Climb up the rope, then jump on top of the tree. Note: There is a kite Boss at the very top of the tree. When you first get on the tree, HAM will appear. Find 50 coins bring them to HAM to receive a Pizza Planet token.

Find the green army men:
Begin game play on the Andy's Neighborhood level. After starting, you should see a tractor that will chase you. Do not leave the yard. Turn around and you will see a green army man. Go up the steps and approach him. He will offer a Pizza Planet token to you if you can find all five of his army men. The other army men can be found easier if you see flames.

Run on the top of the roof:
Find all the army men, then climb the house to reach the roof.

Lose lives slower:
Start out on any level when your lives are full, and collect more lives. You will not lose lives as fast after getting hit.

Beat RC without Rocket Skates:
In the neighborhood level, when the race with RC begins follow the track as normal. As soon as you see RC behind you, do your spin attack (down c) and RC will briefly stop. This will give you enough time to take the lead again. Keep doing this and you will win the race.

Beat The Attic Robot:
Inside Andy's house (In the attic) there is a robot you need to beat to get a pizza planet token. You're laser won't hurt him so you need to make him cahse you until he needs to recharge. Then use your spinn attack on him. He will start chasing you again. Repeat the prosses until the robot is dead.

Beat The Slime Boss:
On the Slime boss level, everytime you shoot the slime monster it shrinks down into his trash can. Shoot the slime monster untill it's whole body is in the trash can, it will loose energy by doing this but each time it goes down into the trash can, the slime monster gets bigger so it takes more time to shrink it down. Just get it down in the trash can about four times, then it will die.

Multi-player characters:
Successfully complete the game with all Pizza Planet tokens collected. Then, return to the first level and speak with Buzz, Ham, Mr. Potato Head, Slinky, and Rex to unlock them in multi-player mode. Save the game, then start a multi-player game.
