Good Luck Bloons spawn at the beginning of the path in certain situations in which you have good luck. One of these situations is when you place a "lucky" seventh tower on the screen. At this time, seven Good Luck Bloons appear on the screen. Good Luck Bloons can help in three different ways. If you destroy them, each one gives you $75. If you allow them to escape, each one gives you 2 lives. They can also help by destroying Bad Luck Bloons - if these two types of bloons come into contact with each other, both are destroyed.
