2. Guess the Summerween Picture
An eerie-themed picture reveal game is perfect to find out if your team can spot some ghoulish images hidden in plain sight. Teams are shown various Summerween-inspired pictures, disguised by filters like cropped movie stills, zoomed-in treats, and blurred decorations. They need to carefully examine each image and identify it before anyone else to score points.
Check out these sample image category ideas to get started:
- Blurred Movie Stills: The beach scene from The Goonies, the Sanderson sisters flying from Hocus Pocus, or Wednesday Addams’s dorm room.
- Cropped Treats: Candy corn, a mummy hot dog, or a pumpkin-shaped cookie.
- Zoomed in Decorations: A pumpkin beach ball, ghost garland, or Jack O’ Melon.
- Pixelated Accessories: Witch hat, bat-shaped sunglasses, or pumpkin-themed flip-flop.
3. Spooky Costume Party
A themed costume party is a fun way to bring your team together for a Summerween celebration. Instead of traditional Halloween costumes, you can follow a ‘summer meets spooky’ theme to create fusion outfits that blend the best of both worlds. Add fun elements like DIY mocktail stations (send kits to remote employees), costume parades, trivia games, and a best-dressed contest to elevate the vibe of the event. Also, set up a physical (or digital) photo booth with themed props for everyone to take pictures during the event.
Here are a few Summerween costume ideas for your party:
- Surfing witch with a tropical dress, a surfboard, flip-flops, and sunglasses.

- Tropical vampire with a dark floral button-down shirt, shorts, a long cape, and fake fangs.
- Ghost cruise captain with a white uniform and ghost-inspired makeup.
4. Pumpkin Patch Murder Mystery
If you’re looking for thrilling Summerween ideas, Murder! At The Pumpkin Patch is a fun way to turn your team into detectives for an hour. The Harvest Hollow’s Annual Fall Festival is canceled due to the death of a harsh festival critic. You and your team need to join the Skellington Police Force to interrogate live suspects like the baker, mayor, bar owner, and crime writer to identify the culprit.
A few months ago, we played this hosted game and had an amazing time questioning the suspects. Each team had a different theory, and the story became more intriguing with each new clue. Finally, one teammate spotted a loophole in a suspect’s story and cleverly unveiled the culprit. The live actors, unexpected twists, and collaborative sleuthing work kept each one of us hooked from start to finish.

5. Spooky Mocktail Lab
A spooky mocktail-making session is a fun addition to your team’s Summerween ideas for mixing Halloween-in-July-inspired beverages with coworkers. Teams use fresh seasonal fruits, flavored syrups, edible glitters, and themed toppings to create their drinks. To dial up the fun, run a mocktail-making competition, have everyone vote for the best entries, and award themed prizes, trophies, or gift cards to the best ones.
Check out these delicious mocktail ideas:
- Black lemonade (lime juice, food-grade activated charcoal, water, simple syrup, ice)
- Blood orange spritzer (blood orange juice, sparkling water, lime juice, orange slices, ice)
- Glow-in-the-dark mocktail (tonic water, lime juice, simple syrup, club soda, ice)

- Ghostly coconut cooler (coconut water, coconut cream, pineapple juice, lime juice, ice)
Here’s a tip: If you’re hosting this event in-person, set up multiple drink stations around the workplace. For remote and hybrid teams, send mocktail kits with pre-batched supplies to make participation easy.
6. Summerween Happy Hour
For teams that want to enjoy a Summerween sundowner, a Halloween-inspired happy hour with themed-cocktails is the perfect way to celebrate with your team. You can spruce up a designated space with decorations like Jack O’Melons and tropical decor, or use a themed virtual background to set the event’s backdrop. Serve refreshing cocktails with a Halloween-in-July twist, like Blood Orange Spritzers or Vampire Mai Tais for teams to enjoy while connecting with coworkers.
To keep it lighthearted, add fun elements like trivia games, bingo, cocktail-garnishing contests, and best-costume awards to keep everyone entertained throughout. Teams can also enjoy a hands-on, hosted mixology session to learn how to create drinks from scratch and find new favorites along the way.
Here’s a tip: Offer zero-proof cocktail alternatives to team members who do not drink alcohol, so everyone can enjoy the experience together.
7. S’mores Social
S’mores social combines everything people love about summer campfires with a ghostly Halloween-in-July vibe. Set up a DIY s’mores station with marshmallows, graham crackers, chocolate bars, caramel sauce, and assorted toppings so team members can customize their treats.
Once the treats are ready, gather around a real or artificial campfire to share ghost stories or personal experiences, adding a touch of mystery to the event. To recreate the camping vibe, play ambient sounds like crackling fires, crickets, and owl calls, or eerie background music for an immersive experience.
Try this: If you have a remote or hybrid team, join a hosted Virtual S’mores Snickerdoodle Cookies Making to enjoy the experience together.
8. Trick or Treat Cookie Decorating
Summerween cookie decorating becomes even more fun when you add a trick-or-treat element to the activity. Before the event, have team members choose from a pile of trick-or-treat cards or let them spin a digital wheel if you’re hosting online. The cards may contain bonuses or silly decorating challenges to make the activity more unpredictable. Your goal is to decorate plain cookies with Summerween-inspired designs like beach ghosts or skeleton surfers while completing your bonus task.
For treat cards, you can add these tasks:
- Add candy eyes to your design.
- Get a free design hint from the host.
- Swap your task with a coworker.
For trick cards, you can add these tasks:
- Decorate using only two colors.
- Include a ghost somewhere in your design.
- Add beach elements to your cookies.
Pro tip: Look for hosted cookie-decorating events with customization options so you can run the event without worrying about planning and execution.
Creative Summerween Ideas
Creative Summerween ideas are perfect for teams to create crafts or decorations, or paint something together. It’s a low-key, engaging way to celebrate the holiday with your remote, hybrid, and in-person teams.
9. Jack O’ Fruit Carving
Pumpkin carving is a Halloween classic, but pumpkins aren’t typically in season during summer. So why not swap them for fresh seasonal fruits and host a Jack O’ Fruit carving session for a summery twist on the beloved tradition? Team members carve watermelons, pineapples, cantaloupes, or squash to create spooky faces together. Participants can also use props and decorations like sunglasses, flower leis, beach hats, glow sticks, and fairy lights to make their carvings stand out.
To add personality to your creations, dress them up as beach ghosts, haunted tiki masks, vampire pineapples, or tropical witches. You can display the finished pieces in a common area or create a digital gallery for everyone to check out and appreciate each other’s designs.
Try this: If you’re not looking for a self-hosted event, join a guided fruit carving class with kits to learn how to carve fruits from an expert.
10. Ghostly Desk Makeovers
Not all Summerween ideas have to be elaborate to be fun, and desk makeovers are one such simple activity for teams. Challenge your team to transform their desks, cubicles, or home workspaces into Halloween in July displays. Encourage everyone to get creative and bring out summer-inspired decor with eerie twists to decorate their spaces (because who wouldn’t like a ghost in sunglasses at their desk?). You can also run a live poll where everyone votes for their favorite decorations and awards fun titles for scariest setups, funniest props, or best Summerween theme.
Here are a few ideas to get started:
- Create a mini beach-party scene with toy ghosts.
- Turn your desk into a haunted tiki bar with skeleton bartenders.
- Set up a ‘Ghosts on Vacation’ display with albums, postcards, and suitcases.
- Build a campsite using an artificial campfire surrounded by toy ghosts.
- Assemble a beachside witch’s hut with pumpkins, skeleton garlands, and sand.
11. Glow In The Dark Paint Party
If your team loves creativity, then a glow-in-the-dark paint party is a great idea for your Summerween. Teams use UV-reactive paints to create Halloween in July-inspired artworks that come alive under blacklight. Everyone can paint fun, offbeat scenes like ghosts in grocery stores, or a haunted pool party.
You can also go digital and use AI tools like NightCafe Blacklight Glow Art Generator to type custom prompts and generate luminous artworks. For a more laid-back, social vibe, have everyone bring beverages like neon fruit punch, classic lemonade, or Halloween-inspired cocktails for a paint-and-sip-style experience.
Pro tip: Provide team members with curated kits so they don’t have to source the materials in advance.
12. Ghost in a Jar Diorama
Upcycle your old mason jars into Pinterest-worthy decorations by creating a ghost-in-a-jar diorama with your team. Using simple, easy-to-find supplies like cotton, cheesecloth, Mod Podge, and decorative materials, teams create one or multiple mini ghosts to put inside the jar.
They can even place decorative elements inside the jar, like sand and faux seashells (to mimic a beach) or tiny tombstones and skeleton charms, before suspending the ghost with a clear thread. The finished creation can double as festive desk decor, a dinner table centerpiece, or a gift for loved ones.
