Cheeps are tiny chicks seen in zOMG during Easter events. These tiny chicks would wander around various areas and making loud "cheeping" sounds. When a player clicked a chick, the chick would say a random humorous phrase.
During Easter 2010 & 2011, these chicks could be found in random Easter Eggs that were cracked open. Some of the chicks that were considered rare would be seen wandering around an area alone, and the capturing of these rare chicks would result in them becoming animal companions.
