Skull Emote

The skull emote was an Emoticon a user could use when the went to the emote section on their Toolbar. Towards the end of 2007, Club Penguin removed these emotes from the list because it was "not very appropiate for younger users". In 2008, the heart emote returned, and it was to show friendship. However, the skull emote has not been brought back yet, and it most likely won't. Fortunately, the emote is still used on player cards to ignore players and on your Ignore List.
