21 Trunk or Treat Ideas for Cars That Stand Out

The crisp autumn air, excited little ones in costumes, and a glowing car boot transformed into something magical… this is what makes October feel special. As a mum of three, I know how busy and chaotic life can get. Between school runs, dinner, and last-minute costume hunts. Adding a Pinterest-perfect Halloween trunk or treat to the list can feel impossible.

I’m Charlotte, Family Lifestyle Publisher and Soft Girl CEO of Adore Charlotte. I’ve spent over a decade writing about family life, celebrations, and home inspiration. And I’m here to help you romanticise the chaos. These 21 trunk or treat ideas for cars are cosy, creative, and most importantly—doable on a busy mum’s schedule.

Whether you want sweet and nostalgic or just spooky enough, this list will help your Halloween trunk stand out while keeping things calm and fun.

What is Trunk or Treat?

Trunk or Treat started in the US as a safe and community-focused alternative to traditional trick-or-treating. Instead of going door-to-door, families gather in a car park, decorate their boots, and hand out sweets in one place. It’s become especially popular at schools, churches, and community events because it’s safe, easy to organise, and perfect for little legs that can’t handle a long walk around the neighbourhood.

For mums, it’s a game-changer: you get to be part of the fun without worrying about roads, long walks, or dark nights. Plus, trunk or treat setups are super Instagrammable and Pinterest-worthy. Making them a seasonal tradition families look forward to each year.

21 Trunk or Treat Ideas for Cars

Candy Cottage Boot

this for later

Turn your boot into a life-sized gingerbread house. Foam panels painted like biscuits, colourful paper “gumdrops,” and fairy lights set the scene. A basket of pre-bagged sweets makes it both magical and practical.
Charlotte Tip: Use command hooks and string to hang decorations so nothing damages your car paint.

Disney Frozen Snow Scene

Drape a pale-blue throw, add paper snowflakes, and string cotton-ball “snow.” A few LED icicle lights make the whole scene sparkle. This one’s toddler-friendly and instantly recognisable.
Charlotte Tip: Cotton wool from the pound shop works perfectly for snow on a budget.

Jurassic Park Adventure

All you need is a bold “Jurassic Park” sign, toy dinos, and maybe a cardboard “electric fence.” Throw in a ranger hat and khaki backdrop to complete the look.
Charlotte Tip: Inflatable dinos are a quick win, big impact with no effort.

Cookie Monster Car

Blue fringe or tablecloth strips make “fur,” with googly eyes on cardboard to create Cookie’s face. Add oversized cookie props and a jar of wrapped biscuits.
Charlotte Tip: Cut a cheap blue tablecloth into strips for DIY fringe, it looks like fur for pennies.

Drive-In Movie Night

Make a cardboard marquee and loop old trailers or cartoons on a tablet. Add popcorn tubs for décor (and snacks). It’s cosy, fun, and photo-ready.
Charlotte Tip: Group props in odd numbers (3 buckets, 5 signs) for a balanced look.

101 Dalmatians Pup Party

Dalmatian-print sheets, plush puppies, and a Cruella-inspired scarf make this theme pop. It’s playful without being too busy.
Charlotte Tip: Use black electrical tape on a white sheet for a quick DIY Dalmatian pattern.

Ghostbusters Photo Stop

Add toy proton packs, a green balloon “Slimer,” and a “Who Ya Gonna Call?” sign. Spooky and nostalgic, but family-friendly.
Charlotte Tip: A Bluetooth speaker playing the Ghostbusters theme will pull kids straight in.

Minion Balloon Swarm

Yellow balloons with taped goggles and silly faces make a cheerful display. Add banana sweets for extra laughs.
Charlotte Tip: Attach balloons with reusable glue dots, they hold well without popping.

Wizard of Oz Yellow Brick Road

Lay down a yellow runner, create a cardboard Emerald City, and pop a toy Toto in a basket. Instantly whimsical.
Charlotte Tip: Use cardboard sprayed yellow for the “road”, budget-friendly and recyclable.

Toy Story Carnival

Forky pumpkins, bright bunting, and paper-plate Bunny and Ducky make this instantly recognisable.
Charlotte Tip: A Mr Potato Head toy in the boot adds extra charm with no effort.

Harvest Festival Vibe

Hay bales, plaid blankets, and mini pumpkins give a rustic autumn feel. Perfect for church or school events.
Charlotte Tip: LED lanterns tucked into hay add a safe warm glow.

Willy Wonka Wonder

Transform your boot into a magical chocolate factory with oversized candy props, golden tickets, and colourful balloons. Line the space with purple fabric for that Wonka flair and tuck in jars filled with wrapped sweets. This theme works because it’s instantly recognisable and makes kids feel like they’ve stepped into a storybook.
Charlotte Tip: Spray-paint pool noodles in bright colours to look like giant candy canes, budget-friendly and dramatic.

Hocus Pocus

Channel the Sanderson sisters with a cauldron, spell book, and black-and-purple décor. Add LED candles for a flickering glow and drape a broom across the boot. This theme works because it’s nostalgic for parents and fun for kids without being too scary.
Charlotte Tip: Print faux potion labels for old jars, easy DIY props that look Pinterest-perfect.

Pumpkin Patch Car Boot

Fill your boot with pumpkins in different shapes and sizes. Add hay bales, autumn leaves, and fairy lights to make it feel like a mini farm stand. This theme is simple, affordable, and timeless, perfect for families who love the cosy fall aesthetic.
Charlotte Tip: Group pumpkins in odd numbers and at different heights for a polished, photo-ready look.

Noah’s Ark

Use pairs of plush animals to create a trunk that tells the story of Noah’s Ark. Line the boot with blue fabric for “water” and brown cardboard panels for the “ark.” This theme feels wholesome and is perfect for church or community events.

Charlotte Tip: Borrow stuffed animals from home, kids love spotting their favourites in the display.

Trolls Movie Party

Cover your boot in bright rainbow colours, tinsel garlands, and glittery accents. Add Trolls plush toys or print cut-outs of Poppy and Branch. Play upbeat Trolls songs to bring the whole thing to life. This theme works because it’s vibrant, fun, and appeals to all ages.
Charlotte Tip: A rainbow tablecloth makes an instant backdrop, no sewing or fuss required.

Pirate Ship Boot

Turn your car into a pirate’s treasure chest. Add a cardboard sail, a treasure chest filled with gold chocolate coins, and a skull-and-crossbones flag. This theme is interactive and works brilliantly for games like “find the treasure.”
Charlotte Tip: Spray-paint rocks gold and scatter them in the boot for budget-friendly treasure.

McDonald’s Drive-Thru

Make your boot a mini McDonald’s with a printed golden arches sign, burger boxes, and red-and-yellow décor. Hand out toy fries or sweet bags labelled with the logo. This theme is quirky and instantly gets laughs.

Charlotte Tip: Use empty fry boxes stuffed with tissue paper for easy décor that doubles as candy containers.

Hogwarts School of Witchcraft and Wizardry

Transform your boot into the Great Hall with floating candles, house banners, and a sorting hat. Add magical props like spell books and wands. This theme is a crowd-pleaser for Harry Potter fans and perfect for all ages.
Charlotte Tip: Hang battery-operated candles with fishing line, they look like they float in mid-air.

Mad Scientist Lab

Fill your boot with beakers, faux potions, and glowing LED jars. Add goggles, gloves, and a white lab coat draped over a chair. This theme works because it’s playful and slightly spooky without being too much for younger kids.
Charlotte Tip: Use glow sticks in clear jars of water for an instant bubbling “experiment.”

Twister Board Game

Cover the floor of your boot with a DIY Twister mat using white fabric or a paper backdrop and coloured circles. Hang extra dots on string from the top of your boot to make it 3D and playful. Add a cardboard spinner on the side so kids can “spin” while they grab their sweets. This idea works because it’s bright, interactive, and a fun twist on a classic game.

Charlotte Tip: Use paper plates in red, blue, yellow, and green as the dots. Quick, cheap, and eye-catching.
