Billy & Mandy's Big Boogey Adventure is the first Grim Adventures of Billy and Mandy television movie, the second one being Billy & Mandy: Wrath of the Spider Queen. It was also released on DVD. It premiered in the U.S. on March 30, 2007, and in the U.K. on February 14, 2007.
Grim is sued for dereliction of duty by his old rival, the Boogey Man. Grim, Billy, Mandy and Irwin are set to be exiled by the Underworld Court and placed in the custody of Boogey Man. Numbuh 3 of the Kids Next Door is the court-appointed Grim Reaper. Boogey Man reveals his plan is to steal the Horror's Hand, an object capable of transforming its holder into the scariest and most powerful being in existence. The group eventually escapes and plans to obtain the hand for themselves for various reasons.
Both groups eventually reach where the hand is held, Where they meet Horror, a living statue that cut off his hand, and placed his fears within it. To obtain the hand, two rivaling groups must embark on a race across the River Styx, as well as facing their worst fears. Grim and the children eventually find the hand, only to have it stolen by Boogey Man. He is however incapable of facing his worst fear, realizing that he is not at all scary. He suffers amnesia after a series of accidents, and ends up afraid of everything and everyone. Grim is reinstated as the Grim Reaper. In the end, a naked, cut up Billy comes from two weeks in the future to warn that if Mandy had used Horror's Hand, she would have taken over the world in two weeks. He eventually goes back to the future to make sure that things were set right. The credits roll, showing the aftermath for each character.
The epilogue shows how Billy went back to the future, and finds that Fred Fredburger obtained Horror's Hand from Grim's magic trunk and took over the world as the new Lord of Horror.
Production information 
Creating the film was the first time that Maxwell Atoms had created anything with a length of over one hour. That, along with creating the regular season was challenging for him. Boogey Man was chosen as the villain for the film because he was a lesser villain that had a relationship with Grim. This was because Atoms was given the idea to follow a storyline similar to Star Trek II: The Wrath of Khan by a Cartoon Network representative. The role of Numbuh Three was originally supposed to be taken up by Pamela Anderson, but she did not take the part. Afterwards, he decided to use Numbuh Two, who is innocent, as a sneak preview of The Grim Adventures of the Kids Next Door, but ended being suggested by Tom Warburton that Numbuh Three be used instead. Atoms also used some Nintendo cameos in the later part of this TV movie, such as when Boogey Man kidnaps Mandy he makes a "warp pipe" appear and its SFX is used when he goes into it
The title track "Land of the Dead" was written and performed by Voltaire. It is Voltaire's second collaboration for The Grim Adventures of Billy & Mandy, the first being on the episode "Little Rock of Horrors" with the song "BRAINS!".
The DVD was released on April 3, 2007, in the USA. The DVD contains both anamorphic wide screen and modified full screen versions with 5.1 surround sound and regular stereo sound. Special features include the original "Bully Boogie" episode and interviews with the voice actors.
Dennis Prince of DVD Verdict reviewed the movie saying, "All told, Billy & Mandy's Big Boogey Adventure is a gift from Atoms, and an indulgence of all the goodness and gooeyness that has made the series a top draw on Cartoon Network. Despite the boogers, bare buttocks, and boorish humor, this court finds no real crime has been committed. Case dismissed". MaryAnn Johanson, of The Flick Filospher reviewed the movie saying "'Full-length movie. Full of boogers!' promises the blobby green sticker on the DVD. And it's true. But somehow, the tons of gross-out potty humor manages to be delightfully goofy -- perhaps it's the irresistibly cheerful spin cartoonist Maxwell Atoms puts on his demented twisting of kiddie cartoons" It was nominated for an Annie Award for Best Music in an Animated Television Production.
