it's the same boss except you have to hit him 80 times instead of 60. You will go to A0, then A1, A2, A3, A4, B0, B1, B2, and then the boss. Here's what to do: In the world, you will see a crystal, get it or it will disappear!!! Then you will see a door, get it or it will disappear! It's harder to get the door because a guy is right on it. In Level 99, do not beat the level, if you do, you will go to a boss and when you beat him it will say bad ending, find the crystal and gives you the password to level 99. It'll die instantly if you time it right. When the enemies start breaking out of bubbles so fast you can't pop them, it's better to blow the bubble when you're so close to an enemy you're practically touching it. Use the code for stage B2 (DDFFI) to pick any stage except the final boss. You can't select a stage higher than the one the password you used was for.

Push the A and B buttons to change this number and pick a stage.

Stage Select (sort of): After entering a password and selecting the number of players, the stage number appears on the right side. This will also enable the sound test option. Then, pop the bubbles to see the 'Happy Ending'. Surround the enemy in the final level with bubbles, then press Start, Select, Start to bring a second player into the game. Press Start, Select when a player runs out of lives to borrow a life from the player that is still active.
