Halloween Costume Guide
The digital rabbit who hides inside a VR game and whispers that he always comes back.
Glitchtrap lurks inside a VR game as a golden-yellow rabbit in a purple vest, silently watching the player until he has collected enough of their attention to attempt escaping into the real world. The costume’s challenge is the color: most bunny onesies are white or gray, which is why the brief calls for a monkey or teddy bear onesie in a warmer tone. For more on the character’s origins, the FNaF fandom wiki covers his full appearance history across Help Wanted and Security Breach.

The vest is what people see first, and the fit matters more than it does on a normal outfit. A vest that pulls across the chest or rides up over the onesie makes the whole thing look like an ill-fitting joke costume rather than an intentional character. Get the right size before the event, not on the day. If the bunny hat keeps sliding back, a single bobby pin through the base holds it without showing. Without the hat on straight, the costume reads as a generic animal onesie and the Glitchtrap connection disappears.
In Help Wanted, Glitchtrap stands at the edge of the player’s peripheral vision and waves slowly, drawing them closer. At a party, standing just outside a group and doing a single slow wave whenever someone makes eye contact is the most accurate and genuinely unsettling thing you can do in this costume.
Vest Sizing Before You Order
Most people underestimate how much bulk a onesie adds. Measure around your chest while wearing the onesie, not your usual size, before ordering the vest. A vest that fits over a t-shirt will likely not close over a full onesie. If it arrives and is too tight, the onesie compresses and the costume loses its shape within the first hour of wearing it.
The Two Black Buttons
Glitchtrap has two black buttons near the top of his chest in every appearance. It’s a small detail but one that FNaF fans will notice immediately. Two large black buttons sewn or pinned to the front of the vest takes five minutes and adds a level of accuracy that reads well in photos. Skip this and the vest looks generic.
FNaF Full Crew
Strong group for any crowd that knows FNaF beyond the original four animatronics. All five characters have distinct enough designs that the group reads as a deliberate FNaF lineup rather than a random collection of mascot costumes. Glitchtrap is the most unusual looking of the group, which actually works in his favor visually.
Creepy Digital Villains
Conditional group concept built around digital or internet horror. Herobrine and SCP-049 are well known in their communities but draw blanks from people outside gaming and online horror. Sweet Tooth broadens the appeal slightly with Twisted Metal’s mainstream recognition. The group works well at a gaming or convention event and less so at a general party.
Horror Game Icons
Conditional group concept that requires everyone in it to own their character fully. Silent Hill Nurse and Morrigan Aensland carry the most immediate recognition. Knight Artorias and The Legion are niche enough that they need the better-known characters nearby to read as part of a horror game group rather than random costumes.
Unhinged & Chaotic Characters
Weak group concept for a general crowd. Glitchtrap and Circus Baby are recognizable to FNaF fans, but Blanka from Street Fighter is a different franchise entirely, and the three together don’t share a visual or tonal thread that reads without explanation. At a gaming event with a broad audience, it might land. Everywhere else, you’ll be explaining the group all night.

Most of this costume is purchased rather than built. The one area where a small DIY effort makes a real difference is the vest detail.
Glitchtrap barely speaks. His entire known dialogue fits in one sentence. The performance is physical, not verbal.
You need a yellow or warm-toned onesie, a bunny hat, an oversized purple vest, a purple bow tie, brown paw gloves, and brown paw slippers. The vest and bunny hat are the two essential pieces. Without both, the costume reads as a generic animal onesie with no FNaF connection.
“I always come back. Let me out.” said quietly near someone’s ear is the one delivery worth attempting. The second quote, from the Pizza Party minigame walls, works best as a deadpan non-answer to something someone says to you at the party.
It depends heavily on the crowd. FNaF fans will recognize it immediately, but at a general Halloween party, a golden rabbit in a purple vest is not an obvious reference without context. At a gaming convention or in a FNaF group, recognition will be high. At a mixed party, expect to explain it several times.
Most bunny onesies are white or gray. Glitchtrap’s base color is golden-yellow, and monkey or teddy bear onesies come in tan and warm-brown tones that are closer to the character. The bunny hat handles the ear detail, so the onesie just needs to get the base color right.
A mid-range purple works. Glitchtrap’s vest has star speckles in the games, but a plain purple vest reads clearly enough in costume. Having the bow tie in the same shade helps the two pieces read as a set.
Yes. The onesie and paw accessories make it comfortable and warm for trick-or-treating, and the look is more cute-creepy than outright scary. The character is from a horror game, but nothing about the costume itself is graphic.
Add two large black buttons to the front of the vest. It is Glitchtrap’s most specific chest detail and takes about five minutes with a needle or a pin. Drawing thin stitch marks on the back of one paw glove also references a detail from his in-game model that FNaF fans will notice.
Official FNaF guides including the Ultimate Guide and the Official Character Encyclopedia have directly identified Glitchtrap as a digital manifestation of William Afton. His phrase “I always come back” is associated with Afton across the franchise, and the beckoning gestures he performs in Help Wanted mirror how Afton lured children in earlier games.
