Calleo is the brother of Ceegee. He has a son named Kalleo and a nephew named Keegee. He was made when Ceegee found the Weegee Cloning Machine in the Fakegee Dump and filled it with FFR so a Malleo clone would be created. While the Gralleo clone was being made, he played the song "C is for cookie", so that way Calleo would be made. He was then killed by Negative Ceegee.
