|2||"Billy & Mandy: Wrath of the Spider Queen"||July 6, 2007|
On a rainy day, giant spiders appear in Billy and Mandy's school and start kidnapping the children one by one. Grim presumes this is somehow related to his past, but does not figure it out until he receives a message saying that Velma, the Spider Queen, an old good friend from high school, is responsible for it. Meanwhile, Billy meets with Jeff the Spider, who informs him that he is precisely marrying Velma. After trying to recover a talking carton of chocolate milk from Jeff, Billy and Jeff get into a fight, and Jeff looks angrier than ever before.
Upon meeting in the school's football field, Velma tells Grim that she has finally come to devour his skull and absorb his magical and supernatural powers, since one hundred thousand years ago, Grim had cheated and robbed her from the possibility of becoming the Reaper in a scare election. Converting the school into her own palace, and with help from the Dark Elves, Velma captures Mandy, Mindy, and Grim, and proceeds to devour the latter's skull. When Velma cracks open Grim's skull, his thoughts start coming out in the form of light blue light, and she is able to see his past memories.

It is revealed that an election was held in the Underworld's high school to choose the Reaper, in which students had to vote on the scariest participant. Velma was the scariest contestant and she was getting most of the votes over the pathetic Grim and the Boogeyman. Boogey decided to tamper with the ballots, and Grim in turn decided to help Velma by filling the ballot with votes for her, but she got the impression that Grim was the cheater and ran away. In a fit of anger for what Boogey had caused, Grim used the prototype scythe in a spectacular fashion to scare Boogey off. The people that had not yet cast their vote voted for Grim, who became the new Reaper. While the story is being told, Mandy and Mindy form a temporary alliance to fight the spiders, and also Billy conquers his arachnophobia, and fights the spider-cow centaur-like extraterrestrial from the milk carton.Velma realizes she was wrong, with respect to Grim, and she apologizes for the whole vengeful ordeal.

|While Billy's Dad is underwear shopping, Billy wears his dad's lucky pants, and accidentally rips them with Grim's scythe. He calls Ed, Edd n Eddy, and they recommend Kids Next Door for charity. Numbuh 1 disguises as Billy while Billy is taken back to the Deep Sea Lab. Mandy arrives at Billy's house and knows Numbuh 1 is not Billy, and tortures him into revealing the truth. Meanwhile, the Delightful Children from Down the Lane and Billy accidentally fuse with the scythe's power to create the Delightful Reaper. Mandy takes over the KND by fooling Numbuh 362 and the rest of the KND, but Numbah 5 knows she is not Numbuh 1, but is taken to the med lab.
