The story: We see someone steal a piggy bank in Tara's bedroom. Noticing the theft is Superman, who emerges from a DC comic book. He calls for the heroes who were hidden everywhere (Iron Man as a lamp, Optimus Prime as an alarm clock, He-Man as an action figure, Wolverine hides under the pillow, Turbo Teen hides under the bed and morphs into Brett, Lt. Dirk Courage is hidden in a Spiral Zone official VHS, The Brave Little Toaster as a pillow, Jem and Kimber are hidden inside a record player, Ripster and Streex are ruining the wall, etc).
We see that it is revealed that the culprit of stealing is Michael, who is stealing drugs, its contents. Ripster smashes the box, unleashing Smoke, the main evil of the series. Our heroes escape with Michael, and go everywhere, including Gotham City, where Batman teaches him the Wonderful Ways to Say No, through a rap-style song.
After the song is complete, they go to the sea where they find Bucky O'Hare and his companion Deadeye Duck, who are after Smoke for a long time.
With Arthur and his Knights of Justice, Michael manages to defeat Smoke by not believing in drugs.
Sailor Moon celebrates with one last song for our heroes, some who have not sung before.
