Complete a level with full HP (receive no damage) to get a Laser Beam (Blip) or a Flamethrower (Blop) for the next level. They are very useful for bonus levels to get extra help on the following levels.
Evade his fire attacks and only attack him when he is turned. Once he is weak he will use a strong combo which will cover the entire screen if completed and take off two on you if it hits. He will launch various fireballs. Try getting laser beams to take off damage. This Boss normally requires two to four lives to kill.
During single player mode, you can get more firepower and more lives by setting the controls of both players to be exactly the same. For example, player one - Fire=Space and player two Fire=Space. By doing this, you can focus on one blob, but the other blob will move with and shoot with you. This kills more enemies and gets you to higher levels. A great idea is to set the special key to a different button for each player so that you can get double the cow bombs.
