A 2001 Halloween MadeForTVMovie by ''Literature/{{Goosebumps}}'' author, Creator/RLStine and notable for starring Creator/ChristopherLloyd.

Danny Walker has moved back to the small town of Walker Falls with his father, James, who hopes to restart the family chocolate business and revive the town as a Halloween tourist destination.

The town, however, doesn't like the idea...or the Walkers...or Halloween, as they haven't celebrated it in quite some time. The sole exception is Danny's grandfather, Uncle Fred, an eccentric sort who likes doing things that most adults would consider childish (playing with toys, dressing up in silly outfits, etc). Danny soon learns the people shun Halloween due to a "curse" by someone named Curtis Danko, an artist outcast who liked to paint monsters. Curtis mysteriously died inside the school kiln while making a sculpture for a contest. Mike Kankel, one of the people who ''really'' opposes Halloween, apparently saw the sculpture himself and was blinded by it. The town's been in fear of Halloween since.

However this particular year brings a slight change, starting when a pile of pumpkins mysteriously appear in the Town Square. However Uncle Fred, while investigating the pumpkins, accidentally sends the whole pile falling on him, killing him in the process. But the next day he reappears in his house still alive...somewhat. He's somehow come back as a zombie, and he isn't the only one resurrected as well.

It soon falls on Danny, his love interest, Dayna, James and Uncle Fred to figure out what's going on before the whole town is overrun by zombies.

!!''When Good Ghouls Go Bad'' has the following tropes:
* AllOfTheOtherReindeer: Outside of his family, Danny is not liked by anyone in Walker Falls. He has that in common with Curtis Danko, who was an eccentric goth with a passion for art.
* AnArmAndALeg: Happens to Uncle Fred a few times after he turns into a zombie.
* BittersweetEnding: [[spoiler:The town, upon knowing the truth behind the kiln incident and that the Curtis Danko curse is bunk, resume celebrating Halloween. However, while he was able to mend his relationship with his son, Uncle Fred is still a zombie and has to pass on with the others.]]
* DarkIsNotEvil: [[spoiler:Curtis Danko turns out to be this. He was actually nice guy who admired Uncle Fred and made a statue in his honor. However, the JerkJock in his school accidentally got him killed and tried covering it up.]]
* TheDeadCanDance: The finale sees the zombies doing this, ballroom-style [[spoiler:before they wither to dust.]]
* DeadlyPrank: [[spoiler: The real truth behind the kiln incident was that Curtis had ran into the kiln to hide from Mike and his fellow bullies. They locked him inside, intending to release him later. But the janitor happened to come back and accidentally turned the kiln on, wearing headphones so he couldn't hear anything, burning Curtis alive.]]
* EarAche: [[spoiler:When Mike Kankel's zombie father shows up to punish him. He drags away Mike like this (the "like a naughty child" version).]]
* EvilIsPetty: [[spoiler:Mike Kankel admits that he scared the townspeople into not celebrating Halloween when he saw Curtis's statue which was of Uncle Fred, who had given donations to the school's art and music programs and was loved by the town children, largely out of spite and jealousy when he wouldn't give them money to build a football theme park.]]
* EstablishingCharacterMoment: The first time we see Uncle Fred, he's fallen asleep at the kitchen table wearing a space suit.
* EyeScream: What Mike claimed happened when he saw the "cursed" statue of Curtis. [[spoiler:He's lying, the statue was normal and he covered his eyes in soot to make it seem like his eyes were scorched.]]
* FamilyUnfriendlyDeath: Curtis's [[spoiler: especially when it revealed how he truly died.]]
* FreakOut: Danny several times, most notably [[spoiler: when he finds that his deceased grandmother is supervising the zombie uprising.]]
** Mike upon seeing Uncle Fred "alive" not shortly after his funeral.
* GhostlyGoals: Danny and Dana figure that Curtis Danko and his army of zombies want to reclaim his stolen statue and punish the townspeople. [[spoiler:As it turns out, what he really wants is to show them his art project and expose Kankel's lie.]]
* GlowingEyelightsOfUndeath: Curtis Danko has these via a pair of magic fireflies.
* HauntedHouse: Dayna and the other kids set one up in [[BigFancyHouse an abandoned mansion]] so they can have Halloween despite the town's fear of the curse.
* HeadphonesEqualIsolation: [[spoiler:The janitor wearing them is what turned the klin prank into a full-on DeadlyPrank.]]
* TheHermit: After what happened, Uncle Fred shuts down the factory and becomes a recluse.
* HeroWorship: Of sorts. The contest involved students making a statue based off their personal hero. [[spoiler:Curtis's was of Uncle Fred while Mike did his of his father.]]
* ItsAllAboutMe: [[spoiler:Mike would rather ruin Halloween for Walker Falls, damage the reputation of a kind and respected town figure, and let the town fall into the hands of zombies than admit that he let an innocent student die in a kiln accidentally and exploited this death for the aforementioned ruining because he didn't get a football-based amusement park.]]
* ItsAllMyFault: Uncle Fred blames himself for the death of Curtis Danko because he donated the kiln the boy died in.
* JerkJock: Mike Kankel, as well as his son Ryan. All the Kankels can think of is football, and deem anything not regarding sports as trash worth terrorizing people over. This is much more important to the plot than it seems.
* TheLastDance: Literally: [[spoiler:After Curtis Danko's UnfinishedBusiness is over and it's clear that the magic that is keeping them alive will be over soon, the zombies spend their last hours dancing before turning to dust at sunrise. Uncle Fred waltzes with his long-dead wife.]]
* LoserSonOfLoserDad: Because it was Uncle Fred who donated the kiln that killed Curtis Danko and started the [[spoiler: alleged]] curse, the entire Walker line has been shunned by the entire town.
* ManChild:
** Uncle Fred, despite being Danny's grandfather, is full of childlike playfulness and a love for pranks.
** Mike is pretty much all the clichés of a high school football-playing bully in a grown man's body. [[spoiler:It seems that keeping the truth about Curtis Danko's curse buried taxed him mentally and emotionally.]]
* MisunderstoodLonerWithAHeartOfGold: [[spoiler:Curtis Danko. He didn't have share any interests with the rest of his classmates and he had a dark taste in art. If he hadn't died in such a tragic way, things would have turned out differently for him.]]
* OurZombiesAreDifferent: And pretty lively too.
* RedEyesTakeWarning: Well, green eyes in this case as they're made from fireflies, but Curtis Danko gives a good allusion to them.
* SmarterThanYouLook: Despite being called "Darklord of the Stupid" by Uncle Fred, Ryan Kankel is much more eloquent and sneaky than your average JerkJock.
* SpiritualSuccessor: ''WesternAnimation/ParaNorman'' can be considered one to this film as they have roughly the same plot.
* TownWithADarkSecret: [[spoiler:But not the secret they thought.]]
* UndeathAlwaysEnds: [[spoiler:After Curtis Danko's UnfinishedBusiness is over and the people of Walker Falls understand the miscarriage of justice they had let occur for so long (and decide to start celebrating Halloween again), he and all of the rest of the zombies (including Uncle Fred) finally turn to dust as the sun rises.]]
* UnfinishedBusiness: [[spoiler:All Curtis Danko wanted to do was show off his completed statue and out Mike for what he had done.]]
* TheVoiceless: Curtis Danko never speaks throughout the film.
* WellDoneSonGuy: Uncle Fred spent so much time concerned with his business and charity work that James began to believe that other people's kids were more important to him than his own.
* ZombieApocalypse: [[spoiler:Subverted, all the zombies are friendly and are helping Curtis to expose Mike Kankel's lies so the town will resume celebrating Halloween.]]
