A Creator/HannaBarbera series [[FollowTheLeader similar to]] their earlier success ''WesternAnimation/ScoobyDooWhereAreYou'', ''The Funky Phantom'' features three teenagers Skip, April and Augie and their dog, Elmo. While trying to get out of a storm, they entered an old house where the longcase clock was wrong. Upon setting the clock to midnight, they released two ghosts: Jonathan Wellington "Mudsy" Muddlemore, a ghost from UsefulNotes/TheAmericanRevolution, and his cat, Boo. The two of them allegedly hid inside the clock from the British during the Revolutionary War, but then couldn't get out and eventually died inside. Ever since being freed by their new friends, Mudsy and Boo have accompanied them on many mysteries, always giving an invisible helping hand.

The show--Hanna-Barbera's first series with animation farmed out overseas (Air Programs in UsefulNotes/{{Sydney}}, UsefulNotes/{{Australia}})--aired on Creator/{{ABC}} in 1971. The voice of Mudsy, provided by Creator/DawsButler, was identical to his voice work for the character WesternAnimation/{{Snagglepuss}}. Butler went so far as to include Snagglepuss' {{catch phrase}}s, such as [[VerbalTic appending sentences with the word "even"]].

!!''The Funky Phantom'' provides examples of:

* AscendedExtra[=/=]StalkerWithACrush: In the Gold Key comics, Mudsy had one in the form of Revolutionary War belle spirit Priscilla Atwater.
* BeautyBrainsAndBrawn: Utilized to an extent but variable. In that Augie isn't always that dumb and that Skip isn't always that nerdy.
** Skip: Brains
** April: Beauty
** Augie: Brawn
* BeachEpisode: "Haunt-In Inn" has a beach scene with the guys in swimsuits and April in a bikini.
** Bonus for {{Fanservice}}, the same episode has April in a nightgown that appears just as short as her usual skirt
* BlondeBrunetteRedhead: April, Skip, and Augie.
* CatchPhrase: Mudsy's "It's Funky Phantom time!"
* ComicBookAdaptation: Eleven issues by Western Publishing Company's Gold Key division (March 1972 - March 1974).
* CoolCar: The Looney Duney and the car they build in the first episode.
* DangerouslyShortSkirt: April's skirt is too short for comfort.
* ExpositoryThemeTune: There were two--one [[DoItYourselfThemeTune performed by the kids]] and another (after three episodes) by some studio performers.
* {{Expy}}: Mudsy's voice is being done in the same way as WesternAnimation/{{Snagglepuss}}, even down to the same verbal tics. But that is really as far as that goes between the two characters.
* HeadlessHorseman: An episode features one as the monster of the week.
* KnowNothingKnowItAll: Mudsy sometimes acts like this. He sometimes goes on about speeches of things he claims he totally witnessed when alive that the kids call out that is not what the history books said happened.
* LoveTriangle: Possibly one of these with Augie, April, and Skip. Augie and Skip fight for April's attention and she seems attracted to them both to a certain extent.
** Played with that in one episode Augie and Skip gravitate to a different girl making April jealous. And when April gravitates to another guy, Augie and Skip are united in getting their girl back. This no doubt leading to OneTrueThreesome ideas.
* MagicSkirt: April jumps up and down wearing a pleated cheerleader skirt in "Pigskin Predicament", and it does not flip up.
* OriginsEpisode: One episode features a flashback to show how Mudsy and Boo ended up in the clock.
* OurGhostsAreDifferent
* PunnyName: Henry Fowler, who runs Chicken Delicious, and Mr. Angus, who owns an angus and roast beef chain.
* ScoobyDooHoax: Originally played very straight but averted in a few episodes, one of which had mundane thieves and another had a gimmick supervillain more in line with something out of ''WesternAnimation/DynomuttDogWonder''.
* ScoobyStack
* SealedGoodInACan: Mudsy and Boo die in the clock. When the kids find it try to fix it (bad enough the clock door got stuck but the time wasn't even right) they released Mudsy and Boo who become their friends, which Mudsy uses his powers to help them.
* TheSmurfettePrinciple: April is the only girl in the group.
* TeamPet: Elmo and Boo.
* TitleScream: They scream the title at the end of the opening.
* TwinSwitch: The Hairy Scary Houndman dognaps Elmo instead of the prize winning dog.
