Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday is an alliance of villains formed during a meeting held at the Mooninite's moon base during The Last One. They were brought together by The Mooninites for "the bruising of the Aqua Teens' asses". Most of them didn't even know why they were there, many of them aren't even hostile to the Aqua Teens, and a majority (the Frat Aliens, the Tree People, the Leprechauns, Romulox, the Dumbassahedratron, Oog and MC Pee Pants reincarnated as a worm) were actually killed during the meeting or on the way to it.

The remaining seven actually arrived to the Aqua Teens' house for a confrontation with them but it is unknown whether the others will reappear with the group at some other point given the general lack of continuity of death in ATHF.

Emory and Oglethorpe were pointedly not invited ("Plutonians are teh suck"), though they insist they are forming their "own league" along with the apparently also-uninvited Jiggle Billy as "Pledge Chairman", still headless from his suicide attempt at the end of Dumber Dolls and still fixated on jiggling.

Their name comes from one of the few things the Rabbot can say (along with "1-2-3-4-5-6-7-8-9-0"), which they ended up picking because it sounded "identifiable" to Err. The Brownie Monsters originally named the group CLICK-CLICK-CLICK-CLICK-CLICK but were executed by the Quad Laser for doing so. When the group finally arrived on Earth to attack the Aqua Teens (by throwing a screw at their house), Frylock promptly blasted Happy Time Harry with his eye lasers, causing Ignignokt to flee in the ship, leaving everyone else stranded on Carl's lawn.
