Fred, Scooby, Shaggy, Velma, Daphne and Fred and others in “Unfinished Business”

Now, let's see who's really behind the evil ska music. Rude Boy is actually... (unmasks the Zombie Rude Boy)

Rude Boy?

You're alive! But the plane crashed 30 years ago.

Velma

Was an elaborate hoax, wasn't it, Mr. Rude Boy?

Oi. You blighters got it in for me, right. But yeah, we faked the whole bloomin' thing. All I ever wanted to do was play ska and be super rich and super famous. But apparently, it just wasn't in the tarot cards, maybe the fact that we only had one song had something to do with it. So me and me mates, the Ska-tastics here, we decided we'd fake our own deaths. Then, we could write the perfect song and return to take the music world by storm.

Martha Quinn

I don't understand, Rude Boy. Why did you wait 30 years to make a comeback?

Ah, don't be such a muppet, Martha Quinn. We planned to be only gone one year, but writing the perfect song took bloomin' forever. By the time we'd cracked it, ska wasn't popular anymore. But everyone loves the undead. So, we began dressing as zombie mogs, riding our undead scooters and wearing polycarbonite-lined skull masks to hide our identity.

Velma

So, in the end, desperate for success, Rude Boy and the Ska-tastics unleashed a dancing plague on the world using an inharmonic chord with special frequencies designed to induce post-hypnotic suggestion to sell their music.

Just as I thought, but didn't say. Dance them away, Sheriff. We are done here.
