Instructions
Complete the "Biolizard" stage before you reach the last battle of the game. Run from the mouth of the Biolizard but not too far. If you run too far, you will run into Biolizard's tail and it will damage you. Stay aware of the gaps in the circle; some parts of the circle have water openings. Jump over those openings. Do not pick up too many rings when you are in a battle. Save some rings for when you need more life.
Run continuously until the Biolizard gets weak and tired. When he stops, run toward his head. Jump and home attack the railing along aside his head. This will help you lift on the top of the railing with speed.
Jump off, then home attack the red button once you're near the top. After Biolizard strikes for the first time, he will start firing energy balls toward you before becoming tired again. Jump if the energy balls are coming from the ground. Perform a somersault if the power balls are in the air. Repeat the steps to fight him.
Change attack methods. After you strike Biolizard for the third time, your attack technique will change. After he fires the energy balls, a group of pink balls will appear around him. Jump and home attack within the pink balls.
Work your way up toward the top to hit the life support system. Once you do that twice, a bunch of pink balls will rise up and you will too. Gravity will cease. Biolizard has one attack left. Strike twice. There are no more rings left in the air. Work around the pink balls until you are near the center, then finish him off. Wait until a few balls move away. You have defeated Biolizard.
Defeat the final boss. Push the A button to move yourself up. Push the B button to dive. Use the analog to move straightforward. Attack the red, swollen area on the FinalHazard. Dodge the laser, then attack. The more hits that you strike out at FinalHazard, the harder the battle, which means there will be more lasers and balls coming at you. Dodge the balls and the lasers. Attack the FinalHazard again and you will defeat the boss.
