Egg Bois from Hazbin Hotel Halloween Costume Guide

Loyal to a fault. Not the sharpest eggs in the carton. Absolutely willing to be shot by a ray gun if you ask politely enough.

Quick Answer: The Egg Bois Halloween costume is a sentient cracked egg shell with thin black limbs, a top hat, and a face you draw on yourself.
  • Egg Costume (essential)
  • Black Long Sleeve Shirt
  • Black Workout Pants
  • Black Top Hat
  • Black Boots
  • Black Leather Gloves
  • Fabric Marker Set (essential)

The Egg Bois follow Sir Pentious around, take his orders without question, and occasionally leak critical intelligence to him by accident because keeping secrets is not something they are capable of. The egg costume shell is the entire build, and the markers are what make it a specific character rather than an Easter prop with ambitions. Hazbin Hotel Season 1 premiered on Amazon Prime Video in January 2024 (Wikipedia), and the show’s fanbase will place this costume. Everyone else will ask.

  • 1 Egg Costume (essential)This is the entire costume. Everything else exists to support it. Look for an oval egg shape that fits over your torso and leaves your arms and legs free, because those black limbs sticking out of the shell are part of the look. If the shell is too small to draw on clearly, or too rigid to sit naturally, the whole build suffers.

  • 2 Black Long Sleeve ShirtWorn under the egg shell with your arms visible on either side. Plain black, no logos. Fitted enough that it does not bunch under the costume.

  • 3 Black Workout PantsThe legs sticking out below the shell. Slim or fitted reads more accurately than baggy. Check your closet before buying.
    See on Amazon
  • 4 Black Top HatThe Egg Bois wear a black top hat with a pink or magenta stripe. The hat you buy will be plain black. You add the stripe with a marker before the party. Without the stripe it reads as a prop hat borrowed from any other costume. With it, fans of the show will notice immediately.

  • 5 Black BootsAny low-heeled black boot works. The goal is black feet below the egg shell. Check your wardrobe first.

  • 6 Black Leather GlovesCovers your hands so the all-black limb effect holds from top to bottom. Any thin black glove works. Check your wardrobe first.

  • 7 Fabric & T-Shirt Marker Set (essential)These are what turn a plain egg costume into an Egg Boi. You need black for the crack and mouth, yellow for the eyes inside the crack, and pink for the hat stripe. Do a test sketch on paper with a reference image open before you touch the shell. The crack needs to look like a crack, not like you sneezed while holding a marker.

How to Style the Egg Bois Halloween Costume

The crack needs to look jagged and intentional, not smooth, or people read it as a mark on a prop rather than a face on a character. The yellow eyes inside the crack are the second read that fans will clock, and skipping them means the shell is just damaged rather than characterful. Anything not-black sticking out below the shell, a tan boot, a grey sleeve at the cuffs, breaks the limb effect and makes the whole thing read as a craft project that escaped the house by accident.

Frank, the only surviving original Egg Boi, was accidentally placed in an elevator during a mission and ended up in a room full of Hell’s Overlords. He then spied on one of them, was told by Alastor to keep what he heard between them, went home, and immediately told Sir Pentious everything at bedtime. Pentious did not believe him. The Egg Bois had previously told him that bank accounts are a scam created by the shadow government with the same energy (Hazbin Hotel Wiki). The information Frank leaked was true and turned out to matter. This is the complete Egg Boi experience.

Draw the crack while the shell is flat

Drawing on a flat surface gives you control that drawing on yourself while wearing an egg costume does not. Lay the shell down, sketch the crack lightly in pencil first, then go over it with the marker. The crack should run vertically through the center of the face area, narrowing and widening unevenly. A crack that is too symmetrical looks drawn on purpose rather than broken. Which is exactly what it is, but the goal is for it not to look that way.

Secure the hat before you leave the house

The hat sits on an oval egg shell, which is not designed to hold anything. Two bobby pins or a strip of double-sided tape will keep it in place for most of the night. A hat that slides off every twenty minutes will end up in your bag by 9pm, and then you are just a person in an egg costume with no hat and a story to tell about it.

Egg Bois Group Halloween Costume Ideas

Couples Idea

Egg Bois & Niffty

Might work, but the pairing is conceptual rather than narrative. Niffty and the Egg Bois are both small, chaotic, and loyal to characters who somewhat underestimate them, but they do not share meaningful screen time. At a Hazbin Hotel fan event this reads as a fun pair. At a general party it is two separate costumes standing next to each other.

Duo Idea

Egg Bois & Sir Pentious

Excellent pairing and the only one in this list with a direct narrative reason to exist. The Egg Bois were co-created by Sir Pentious and are loyal to him specifically, following him through turf wars, an invasion of Hell, and his eventual redemption arc. Visually the contrast works: Sir Pentious is elaborate and tall; the Egg Bois are small oval eggs in tiny suits. Anyone who has seen the show gets it immediately.

Egg Bois Sir Pentious

Group Idea: Hazbin Hotel Hell Ensemble

Egg Bois, Niffty, Alastor, Angel Dust, Charlie Magne, Vaggie

Strong group for anyone at the party who watches animated shows on Prime Video. The characters have distinct enough looks that the group reads as a deliberate set, and the Egg Bois function as the chaotic footnote the rest of the cast tolerates. Outside a Hazbin Hotel crowd, expect a lot of polite nodding from people who do not know what they are looking at.

Group Idea: Comedic Demonic Minions

Egg Bois, Niffty, Minions, Dr. Nefario, Vector, Oogie Boogie

Might work, but the visual range here is enormous. Minions are yellow pill-shapes, Oogie Boogie is a burlap sack, Dr. Nefario and Vector are humans in jumpsuits, and the Egg Bois are sentient oval eggs in tiny top hats. The theme of comedic minion energy is real. No one at a party will read it as intentional without an explanation. If your group enjoys explaining the theme to strangers, this is genuinely fun. If not, it is just a lot of very different costumes in one photo.

Egg Bois Halloween Costume DIY Tips

Building the Look

The hard part of this build is not buying things. It is drawing things. The egg costume is cheap and easy to find. Making it look like a specific character from a specific show takes prep time, a reference image, and markers that work on fabric rather than washing out after an hour.

  • Egg costume: buy this. You almost certainly do not own one.
  • Black shirt and pants: check your wardrobe first. Most people have these.
  • Fabric markers: buy the full set. You need black for the crack and mouth, yellow for the eyes, and pink for the hat stripe. Having colors you do not use is better than running out mid-shell.
  • Top hat: easy to thrift or find at a costume shop. Plain black is correct, you add the stripe yourself.
  • Gloves and boots: check your wardrobe. Any plain black version works.
  • Optional Frank build: add a crack mark drawn over your left eye with face paint, and either buy a hat with a single eye design or draw one on the front of the hat with a marker.

Playing the Egg Bois at the Party

The Egg Bois have one defining trait: they say things with complete conviction that range from reasonable to completely unhinged, and they cannot tell the difference between the two. This is a solid framework for the night.

  • When asked who you are: “Egg Boi.” No further context offered. They do not explain themselves either.
  • For character accuracy: deliver opinions on random topics with the same energy as “bank accounts are a scam created by the shadow government” and walk away without elaborating.
  • If you find someone going as Sir Pentious, follow them everywhere and agree with everything they say. This is canon behavior.
  • Frank’s line after nearly dying is “nearly scrambled himself.” Deploy it when the moment arises. It will arise.
  • Prop option: Gaspar carries a Glock 19 in Extraction. The Egg Bois have their own version of this with Sir Pentious’ ray gun. A toy sci-fi gun gives you something to hand to the Sir Pentious in your group and makes the duo dynamic obvious.

Egg Bois Halloween Costume: FAQ

Pull on the black shirt and pants, then put the egg costume shell over top. Draw a jagged crack, yellow eyes, and a mouth on the shell using fabric markers. Add a pink stripe to the top hat, place it on the shell, and finish with black gloves and boots. The markers do more work than any other item in this build.

Yes, within the right crowd. Hazbin Hotel has a very active fanbase and Season 1 arrived on Prime Video in January 2024, which keeps it current. Outside that fanbase, expect people to ask what you are rather than recognize you, which is fine if you enjoy explaining it.

They are not known for memorable one-liners as much as for saying things with total conviction. One told the room that “bank accounts are a scam created by the shadow government,” which Sir Pentious later cited as a typical example of things they say. Frank, the sole survivor of the original group, described nearly dying during the extermination as having “nearly scrambled himself.” The angelic Egg Bois created in Heaven limit their vocabulary entirely to “Eggy,” which annoys Sir Pentious considerably.

They are a group of sentient egg demons who served as Sir Pentious’ loyal minions, debuting in the Hazbin Hotel pilot. They were co-created by Sir Pentious and a scientist named Baxter. Almost all of them were destroyed by Exorcists in the Season 1 finale, with Frank being the only original Egg Boi to survive.

Frank is the only named Egg Boi and the sole survivor of the original group. He has a crack over his left eye like a scar and wears a hat with a single eye on the front. He is also the one who accidentally told Sir Pentious classified information he was told not to share, watched Pentious dismiss it as nonsense, and then watched that same information turn out to be completely true and quite important.

Yes. A plain egg costume does not read as an Egg Boi. The crack, the yellow eyes inside it, and the mouth are the features that make the costume specific to the character. Without them you are wearing an Easter prop with a hat. Use fabric markers and look at the character design before you start drawing.

Extremely well. The Egg Bois are canonically a group of identical minions, so multiple people in the same costume is accurate to the source material. Add one person as Sir Pentious for full effect. Even two or three matching egg costumes reads as an intentional group to anyone who knows the show.
