Featured stories
In Halley's Comics comic book store, a young boy named Stevie catches Sabrina browsing through some comics, completely shocked that a girl is reading comics. She quickly mentions that she's looking for Sonic and Knuckles comics. He thinks that she's just buying them for someone else, but she blows that off, too, gushing about how cool Knuckles is. However, in doing so, she accidentally recites a spell that her cat Salem mentioned, transporting Stevie and herself to Robotropolis. There, they find Sonic the Hedgehog and Knuckles the Echidna facing down Dr. Ivo Robotnik, where the scientist is threatening to kill Tails should he not surrender. However, both Sonic and Knuckles think the universally lost Sabrina and kid are Overlanders, leading Sonic to deal with Robotnik while Knuckles confronts the two.

When Knuckles does so, Sabrina decides to fix things by getting them home. However, she accidentally drags Sonic and Knuckles with her. Even worse, Sabrina remembers that she was going to a Halloween party being thrown by Cheryl Blossom and she was racing this way. Sabrina fixes this by taking Stevie and dressing the two of them in costumes, passing Sonic and Knuckles off as the same. Sabrina is able to pass off the trio and arrive in Cheryl's fancy mansion, where various figures are attending the party, including Archie and his friends and Josie and the Pussycats. However, Sonic and Knuckles are not liking the party at all and it gets even more hairy when Reggie confronts the duo, wanting to see who they were under the costume before Archie is able to pull him away.

With things heating up, Sabrina gets a hold of Salem and alerts him of what's going on. However, when she reveals that she brought Sonic and Knuckles in, Salem teleports to the house... just in time to spot Dr. Robotnik walking out the house. Sonic and Knuckles spot him and jump him, only to reveal it's Jughead in costume. Salem finally teleports the Mobians away and Sabrina erases everyone's memory of them even being there, except for Stevie's. In the end, it was revealed that Stevie was right about one aspect -- she was buying the comics for Salem.
