In Club Penguin, players have the ability to throw snowballs. This is done first clicking the snowball icon in the toolbar (or by pressing the T key), aiming at the target and then clicking it with the left mouse button. When a snowball hits something, it makes a "squish" sound. In addition, some objects around the island can also be interacted with using snowballs in certain ways, such as the Clock Tower.
Snowballs are often used in snowball fights, or when a penguin is annoyed or mad at someone. Another possible usage is to "point" or show other penguins where an object is, such as a pin.
Snowballs are also used to operate certain devices, such as the Island Lifter 3000, the Snowball Power Generator and the watering system which used to be at the Mine Shack. Some of these devices have a main usage in parties, such as the machine at the Cliff, which was used to proceed in the quest of the Wilderness Expedition 2011.
In several rooms or during certain parties, snowballs turn into different items (such as food, bubbles, water balloons, paint balloons, trash, etc.). During Marvel Super Hero Takeovers, snowballs thrown while wearing Super Gloves were given special properties, such as freezing certain targets.
In addition, snowballs thrown by Herbert and Sam the Sasquatch have a unique sprite. While Herbert hits a penguin with a snowball, the player would be buried in a pile of snow.
