The series aired again in October 29, 2010, for the first time since the Cartoon Cartoon show airing, but the title sequence did not play at all and all of the cartoons were three "Billy & Mandy" cartoons from the "Grim & Evil" era. On October 20, 2017, all 26 episodes produced were released on Cartoon Network On Demand, including 13 other episodes made up of segments that aired as separated series, but put together in their original "Grim & Evil" format (two "Billy & Mandy" segments surrounding one "Evil Con Carne", only this time, there are three cases where it is entirely "Billy & Mandy"). They were also listed on the website of The Detour on Teletoon in Canada. On January 8, 2019, Maxwell Atoms confirmed on Tumblr that these 13 extra episodes aired in the United States, but the dates that they aired on are still currently unknown, though it can be assumed that it would be sometime in 2002 and 2003, as the credits for each episode have copyright dates of those years.
