Lock is the best part of any Halloween Town scene, and I will argue that to anyone. He is small, sharp-toothed, and wearing a red devil costume, and somehow he steals every moment he appears in. If you love this film, you know that the little trick-or-treaters are where the fun lives.
So here is a full set of ideas built around him. Some are costumes, some are decor, and some are edible. All of them lean into that cheeky, spooky-sweet look that makes the movie work at both Halloween and Christmas.
1. A Handmade Lock Devil Mask
A homemade mask is the heart of a good Lock look. Trace a long, narrow face shape onto cardstock or craft foam, paint it in a warm red, and add pointed teeth and a smirk with white and black paint.
Use thin elastic or ribbon ties so it sits comfortably, and cut the eye holes slightly larger than you think you need. Seal the paint with a light coat of clear spray, and the mask will survive a whole night of trick-or-treating or a Christmas party.
2. A Simple Red Devil Costume with a Tail
You do not need a fancy costume to capture Lock. Start with a plain red top and pants, or a red hoodie, and add a long, pointed tail made from stuffed felt or a wire-wrapped fabric tube.
Pin the tail to the back of the pants so it can swing. Black gloves and boots complete the outfit, and the whole look comes together for under twenty dollars if you already own some basics, which makes it ideal for kids who outgrow everything fast.
3. Horn Hairstyles for the Full Look
Lock’s hair does a lot of the character work, and you can copy it with a little styling. Section the hair into two small peaks on top, secure each with a clear elastic, and shape them into soft horn shapes with a bit of gel.
Temporary red hair spray gives the whole effect more punch. Wash it out the same night, and the hairstyle looks great with or without a mask, so it works even at office parties where full costumes feel like too much.
4. A Lock, Shock, and Barrel Group Costume
Three friends, three masks, one unforgettable group. Lock wears a devil look, Shock a witch look, and Barrel a skeleton look, and the contrast between the three makes the group easy to recognize from across a room.
Keep the costumes simple so each one reads clearly, and coordinate tones so they look like a set. This works well for siblings or best friends, and it makes for a fantastic group photo, especially against a dark backdrop with a few glowing pumpkins.
5. A Lock Ornament for the Christmas Tree
A felt or painted wooden ornament puts Lock right where the holiday lives. Cut the face shape from red felt, stitch on a small grin and horns, and add a loop of thin ribbon for hanging.
Place it low on the tree where it can peek out from the branches. A few small black and orange ornaments nearby help it blend in, and kids will love hunting for it every time they walk past the tree.
6. A Spooky-Sweet Christmas Tree Theme
Combine both holidays in one tree. Start with a black, white, or flocked tree, and decorate it with ornaments in deep purple, orange, and bright red, plus a few spiral decorations and tiny pumpkins.
Add a spooky tree topper, like a bat or a curved star, and a few strands of warm orange lights. The result feels like Halloween Town in December, and it is a bold way to show off your fandom without needing any official merchandise.
7. A Painted Lock Pumpkin
Pumpkins are a lovely canvas, and Lock’s face translates beautifully onto one. Paint a pumpkin red, then add black eyes, a wide grin, and two curved horns made from clay or paper cones.
Use acrylic paint, which dries fast and does not rot the pumpkin as quickly as carving does. Set it on a porch step or a mantel next to a few real or faux pumpkins, and it will last well into the Christmas season.
8. A Trick-or-Treat Porch Display
Turn your front porch into a mini Halloween Town. Place a few pumpkins, a twisted spiral decoration, and a Lock cutout or painted sign near the door, and add a small bucket of candy.
Add warm orange or purple lights to glow behind the display after dark. It is a simple way to welcome visitors with a bit of whimsy, and it works equally well in October or December, since the film belongs to both.
9. Lock-Themed Sugar Cookies
Cookies are an easy way to bring the character to the table. Use a round or oval cookie cutter, flood the surface with red royal icing, and add the face details with black and white icing once the base sets.
Pipe two little horns on top with stiff icing so they stand up. Let each layer dry before adding the next, and keep a few plain cookies nearby for guests who want to decorate their own at a party.
10. A Treat Bucket Shaped Like Lock
Lock, Shock, and Barrel carry treat bags, so a bucket is a natural fit. Take a plain red plastic pail and glue on felt eyes, a paper grin, and two horns made from craft foam.
Fill it with candy, small toys, or sweet snacks. It makes a fun party favor or centerpiece, and kids can keep it for years, long after the sugar is gone and the rest of the decorations are packed away.
11. A Mantel Display with Figurines
If you collect small figures, a mantel is the perfect stage. Arrange Lock, Shock, and Barrel figurines at different heights, with black branches, a few candles, and a handful of faux pumpkins around them.
Use a dark runner or a layer of black tulle underneath to make the colors stand out. Keep the display limited to a few key pieces so each one gets noticed, and you will have a conversation starter for the whole season.
12. A Spooky Christmas Wreath
Wreaths do not need to be traditional. Start with a black or dark green base, add twisted ribbons in purple, orange, and red, and tuck in small skulls, bats, or a paper Lock face at the center.
Hang it on the front door or above a mantel with a sturdy hook. It signals right away that your home is a little different, and guests who love the film will smile the moment they see it.
13. A Halloween Town Party Setup
A themed party is easier than it sounds. Choose a color palette of black, orange, purple, and red, and use balloons, streamers, and paper lanterns to fill the room.
Serve themed snacks like spiderweb dips and red punch, and add a small table with masks guests can try on. A simple playlist of film-style music sets the mood, and everyone, from kids to adults, ends up playing along.
14. A Photo Backdrop with Lock Props
Photos are half the fun of any party. Hang a black sheet or curtain on a wall, add a few paper bats and a spiral decoration, and set out props like paper masks on sticks and a small sign.
Keep the lighting low and warm so the colors glow. Place the backdrop near the entrance so guests can snap pictures as they arrive, and you will end up with a collection of photos that capture the whole night.
15. A Soft Plush Lock to Sew at Home
If you like to sew, a plush Lock is a rewarding project. Cut two matching pieces of red felt or fleece for the body, add a stitched grin and horns, then stuff it lightly with fiberfill.
Keep the shapes simple so the project stays beginner friendly. A small plush makes a sweet gift or a shelf decoration, and it carries the charm of the character without needing any complicated patterns.
16. Gift Wrap Inspired by the Trio
Wrapping paper is the last place to add personality. Use plain black paper with red, orange, and white ribbons, then add a hand-drawn Lock face or a small cutout on the tag.
Tie the gift with twine or a sparkly ribbon for a mix of rustic and spooky. It costs very little, and the recipient will notice the care, which makes the present feel special before it is even opened.
Final Thoughts
Pick one idea tonight and start it before the week runs away. Maybe it is painting a single pumpkin, cutting a felt ornament, or tracing a mask onto cardstock while you watch the movie for the hundredth time.
Gather what you already own, set a small timer for thirty minutes, and see how far you get. A rough first try is better than a perfect idea that stays in your head, and you will probably find you want to keep going.
