The icy winter icicles are made of bubbles in Bubble Penguin. Use your penguin to knock these icicles down one by one. Here's a special Bubble game Penguin hint to help you on your bubble popping journey: There are three snowball bubble bombs nestled above the icicles. Pop one of these bubble bombs to drop all the bubble around them! This will give you a great direct path to the yummy warm cup of bubble cocoa waiting for you at top!
