Jonathan Wellington Muddlemore, nicknamed Funky Phantom, was the mascot of a teen mystery solving group who appeared Scooby-Doo's feverish dream.
Muddlemore resembles a white human, and wears a 1776 Revolutionary War outfit.
Funky Phantom was tired of being seen as just a sidekick and mascot and became the villain, Lord Infernicus to capture his group, along with the human members of the other groups at the Mystery Solvers Club State Finals and send them to the other side of world, so the other mascots would be helpless.

Lord Infernicus captured all of the meddling kids. Scooby, Jabberjaw, and Captain Caveman see gineua pigs that were wearing the same outfits like the other gangs.
Angel, the principal and Speed Buggy arrived with Scooby, Jabberjaw, and Captain Caveman. Scooby and the sidekicks saved the gang and the day and Scooby unmasked Lord Infernicus, revealing Funky Phantom underneath! Funky Phantom couldn't take it anymore from being a sidekick. He wanted to become the leader of the meddling kids. He created a skeleton fire phantom to scare people away and capture the meddling kids. He even ditched his cat Boo. He then was going to send all the kids to back to Africa where they belong. He then used guinea pigs and made small meddling kids clothes and puts them on the guinea pigs and that way Scooby and the sidekicks will be confused.
He would have gotten away with it if it weren't for Scooby-Doo and his sidekicks. Boo the ghost cat became angry for being lied to and attacked Funky Phantom.
- Funky Phantom says that he wasn't a real ghost, although he's still clearly a spectral being, similar to incarnations of Casper the Friendly Ghost.
- Unlike his original counterpart, he is not called "Mudsy".
- Tom Kenny mimicked original voice actor Daws Butler, who had used a voice similar to his Snagglepuss voice (which was itself inspired by Bert Lahr's portrayal of the Cowardly Lion in The Wizard of Oz); both Snagglepuss and Funky Phantom use catchphrases such as "even" and "heavens to".
