🎃 FRIGHTFUL FLING IV
2 Rooms of Scintillating Halloween Fun!
Saturday, October 31, 2026 | 7 PM – Late
Barrel Proof Lounge | Downtown Santa Rosa
Four years of Halloween mischief, and we're just getting warmed up.
Frightful Fling returns for its 4th annual Halloween celebration, taking over Barrel Proof Lounge with two rooms of music, outrageous costumes, dancing, strange discoveries, and some wonderfully questionable activities.
We're bringing back the infamous Jello Shot Gauntlet, hosting a costume contest with five prize categories, and adding a brand-new photo scavenger hunt to the festivities.
Throw in tarot readings, drink specials, and a building full of people dressed like absolute lunatics, and we've got ourselves a Halloween party.
The fun starts at 7 PM, and we're going LATE!
🎧 TWO ROOMS. TWO DIFFERENT SOUNDS.
🔥 THE LOUNGE
90s & 2000s Hip-Hop • R&B • Throwback Jams
Old-school favorites, forgotten bangers, and all those songs you still know every word to.
⚡ THE MAIN ROOM
EDM • Drum & Bass
Heavy bass, electronic beats, and a dance floor that doesn't know when to quit.
Bounce between rooms, change up your soundtrack, and find your people.
🎭 HALLOWEEN COSTUME CONTEST | 10 PM
Halloween costumes are serious business around here. Well, some of them are.
We're handing out prizes in five categories this year!
💀 BEST COUPLE – Double the creativity, double the trouble.
🔥 SEXIEST – You know who you are.
👽 WEIRDEST – The more bizarre, the better.
🔪 SCARIEST – Give us nightmares.
😂 FUNNIEST – Make us laugh. Bonus points if we can't stop.
Costume judging takes place at 10 PM!
📸 NEW! THE FRIGHTFUL PHOTO SCAVENGER HUNT
We've hidden a little Halloween mischief throughout Barrel Proof, and we're challenging you to find it.
Grab your phone, follow the clues, and track down a collection of objects, oddities, and surprises scattered around the building.
📸 Find the items.
🔎 Photograph the evidence.
🏆 Report back and claim your prize!
Some things will be easy to spot. Others might have you questioning how well you really know this place.
Keep your eyes open. You never know what's lurking around the corner.
🔮 TAROT READINGS WITH RIVER | 7–9 PM
Want a little glimpse into the unknown?
River joins us for special Halloween tarot readings from 7–9 PM.
An established Tarot, Oracle, and Charm reader, River is also an incredibly talented artist and stand-up comedian who has performed right here on the Barrel Proof stage.
She's bringing her cards, her intuition, and her own unique brand of magic to Frightful Fling.
Stop by for a reading and see what the universe has to say.
🧪 THE JELLO SHOT GAUNTLET RETURNS!
Three levels. Mystery flavors. Questionable dignity.
Our ridiculous Jello Shot Gauntlet is back for another round of Halloween nonsense!
Take on a three-level tasting challenge featuring mystery flavors, hands-free slurping, and glow-in-the-dark surprises.
Complete the gauntlet and earn a prize… or at least some highly questionable bragging rights.
Your friends are absolutely going to take pictures.
