"Alright, who plugged the Cacophone in?" This was an idea I got when I was making the previous one. Note the 'hidden' logo. And there's the music teacher as well, but I'm not going to About... him, because I haven't really developed him. He doesn't even have a consistent punny name! Finally, the title refers to the Twelve Tasks that ancient heroes had to perform.
Superheroes in the Gerbilverse: You might think that they'd only save the world from evil geniuses, but there isn't enough of that to keep all the superheroes busy. So they have to save the world from ordinary problems as well, such as unplugging a Cacophone. Ah, the trials.
