1. A Trunk Turned Into A Giant Monster Mouth With Pool Noodle Teeth

White pool noodles cut on an angle look exactly like big goofy fangs, and the dark trunk behind them becomes the throat for free.

Start This Way: Cut 6 white pool noodles into pointy chunks, tape them along the top and bottom edge of the open trunk, and hang a red beach towel inside as the tongue.

2. A Spooky Little Library In The Back Of Your SUV With Old Books And One Flickering Lamp

Stacks of old books from the thrift store do all the work here, and one warm lamp makes the whole trunk feel like a haunted reading nook.

Try This Way: Pile up 15 or so old books in wobbly stacks, drape a dark blanket under them, and tuck one little lamp in the corner so it glows at kid eye level, babe.

Here’s A Great Pick: A Battery-Operated Flameless Candle Lamp flickers like a real flame and needs no outlet, so the trunk glows the whole night without a cord to trip on.

3. A Cozy Campfire Trunk With Fake Logs, Tissue Paper Flames, And Marshmallow Candy

Orange and yellow tissue paper stuffed between a few logs looks like real fire once the sun goes down, and kids always want to warm their hands by it.

Here’s What To Do: Stack 5 small logs in a circle, stuff crumpled orange and yellow tissue paper in the middle, and set a bowl of marshmallow candies on a camp stool.

Here’s A Clever Solution: A Flameless LED Campfire Decoration glows and flickers under the tissue paper, so the fire looks alive even after it gets dark.

4. A Witch’s Kitchen Car Display With A Cauldron, Hanging Herbs, And Jars Of Weird Stuff

Jars of green water with floating gummy worms and some dried rosemary hung upside down are what sell the whole witchy look.

Use This Simple Trick: Set a plastic cauldron full of candy in the center, line up 4 jars of colored water with gummy creatures inside, and tape a few bundles of herbs to the trunk lid.

5. A Car Decorated Like A Haunted Drive-In With A Tiny Movie Screen And Popcorn Buckets

A white sheet pinned flat at the back of the trunk becomes a movie screen, and a spooky cartoon playing on a tablet makes kids stop and stare.

Give This A Try: Pin a white sheet across the back, prop a tablet playing a kid-friendly spooky show in front of it, and hand out candy in striped popcorn boxes.

6. A Pumpkin Patch On Wheels With Hay, Pumpkins, And A Scarecrow Sitting In The Trunk

Real hay smells like fall and covers every ugly corner of the trunk, so you barely need anything else besides a few pumpkins.

Begin With This: Spread one bale of hay across the trunk floor, scatter 6 pumpkins in different sizes, and sit a stuffed scarecrow in the middle like he’s guarding the candy, girl.

7. A Mad Scientist Lab Trunk With Glowing Green Bottles And Bubbling Dry Ice

Green glow sticks dropped into jars of water light up the whole trunk, and a little fog rolling over the edge makes kids squeal every single time.

Here’s A Quick Way: Drop a cracked green glow stick into 5 jars of water, line them up on a tray, and set a small bowl of warm water with dry ice behind them so the fog spills out.

Here’s A Helpful Find: A Mini Fog Machine gives you that creepy rolling fog all night with no dry ice runs or gloves, so the lab stays spooky without the fuss.

8. A Glow-In-The-Dark Skeleton Dance Party In The Back Of A Minivan

Skeletons posed mid-dance with their arms up look hilarious, and a black light makes their bones pop like they’re glowing from inside.

The Easy First Step Is: Pose 3 poseable skeletons in silly dance moves across the open back, play a Halloween playlist on a speaker, and point a black light at them once it’s dark.

One Worth Trying: A Black Light LED Bar plugs into a car charger and makes every white bone glow bright purple, so the whole van turns into a party in seconds.

9. A Spider Nest Car Theme With One Giant Spider And Webs Stretched Across The Whole Back

One huge spider is scarier than 20 tiny ones, because every kid’s eye goes straight to it and the webs just frame it.

Consider This: Stretch 2 bags of fake webbing thin across the trunk opening, then perch one giant spider right in the middle like it just caught dinner.

Here’s A Good Option: A Giant Furry Halloween Spider has bendable legs that grip the trunk edge, so it stays put all night and looks ready to pounce.

10. A Bat Cave Trunk With Black Bedsheets, Paper Bats, And One Purple Light

Black sheets make the trunk look way deeper than it is, and purple light on paper bats gives off that creepy cave glow.

Start Small With This: Tuck black bedsheets over every surface, tape 20 paper bats across the ceiling and sides, and set one purple light bulb in the corner, bestie.

11. A Fortune Teller Tent Car Display With Curtains, A Crystal Ball, And A Bowl Of Candy

Sheer curtains hung from the trunk lid turn the whole back into a little tent, and a glowing ball on a velvet cloth makes kids whisper.

Here’s A Low-Stress Way: Hang 2 sheer scarves from the open trunk lid, lay a velvet throw inside, and set a glowing ball on a small stool with the candy bowl right beside it.

Here’s A Favorite Pick: A Color-Changing LED Crystal Ball shifts through purple and blue on its own, so the fortune teller magic happens without you doing a thing.

12. A Trunk Dressed Up Like A Creepy Carnival Game With Prize Buckets And String Lights

Red and white stripes plus a row of lights is all it takes to say carnival, and a simple toss game keeps the line moving and the kids laughing.

If You Want To Keep It Easy: Line up 3 plastic buckets with point numbers, hand each kid a beanbag, and give candy for every toss no matter where it lands.

13. A Dinosaur Dig Site In The Back Of Your Car With Sand, Bones, And A Shovel

Play sand in a plastic bin with a few fake bones half buried turns candy grabbing into a treasure hunt, and kids go wild for it.

The Most Doable Way Is: Fill a big plastic bin with play sand, bury wrapped candy and a few plastic bones, and set a kid-sized shovel on top with a sign that says Dig Here.

14. A Vampire’s Coffin Trunk With A Black Velvet Blanket And Candy Spilling Out

A trunk is already coffin-shaped, so a black blanket and a pillow at the top make the whole thing click in one look.

Instead, Try This: Drape a black velvet throw over the trunk floor, set a pillow at the top, and let a giant pile of candy spill out the bottom like the vampire’s stash.

15. A Black Cat Cafe Car Theme With Pink Lights And Cat Ears On Everyone Handing Out Candy

Pink string lights and a few stuffed black cats make this one cute instead of scary, which is perfect for the little kids who get nervous.

To Make This Feel More Doable: Wrap pink string lights around the trunk edge, set 3 plush black cats on cushions, and have everyone at the car wear cat ears and whiskers.

A Great Pick For This: A Black Cat Ears Headband Set comes with enough for the whole family, so nobody has to fight over who gets to be the cat.
