Gnarpy is a chartreuse-green, bipedal humanoid cat-like alien with darker green fur patterns on xyr arms, paws, legs, ears, and tail. Gnarpy has four upright cat ears, 2 intersecting each other on both sides of their head alongside four arms. Xyr paws have 4 yellow pads surrounded by a darker green color, with a 4 pointed dark green star pattern on the center pad. Xe also features 6 black whiskers with yellow spheres at the ends on their cheeks and two tails with neon yellow stingers on the ends. Gnarpy has four black almond-shaped eyes, with two smaller than the rest, and a square-like cat smile. Xe also wears sleeveless armour, boots, and armbands with varying colors, though they are usually depicted as crimson. A yellow 4-pointed star is placed on the top right corner of Gnarpy's armor. 

Gnarpy's previous appearance had a blocky model with green fur, alien antennae, and a green tail with a golden glowing tip at the end. Xyr eyes appeared to be slanted in and closed, there was also a yellow star on Gnarpy's chest, and xyr legs had a line pattern. Xe was also "fluffy," having a head, cheek, shoulder, and neck fur. However, Gnarpy's old design was removed due to the original creator's poor reputation and replaced with the current appearance.

In xyr 2024 April Ghouls' Update appearance, Gnarpy no longer has armor and xe only has their top row of eyes, which are moved up to where xyr ears are. Their whiskers are also missing. 

narpy's green spaceship malfunctions in the forest in the Two Stud Camp floor, crashing into the secret area of the camp, where xe will proceed to sneak into the elevator. There is a 50/50 chance for either xe or Spud! to enter the elevator on the floor. If the player throws a Snowball, Tomato, Bowling Ball, C4, using Spray Bottle, or Tiny Foamer on Gnarpy multiple times, xe will zap the player using the star on their armor, dealing 50 damage to them.

Gnarpy is consistently shown in dialogue to be loud and aggressive, thinking of themself as superior to everyone else. Unlike Pest, who acts in a similarly antisocial manner, Gnarpy is never shown to have any friendly interactions with any NPCs, with the only exception being STAT. Gnarpy frequently replaces any "s"s with "z"s in their dialogue, with them occasionally peppering said dialogue with made-up alien words, usually as insults.

Gnarpy will exit the elevator on the Slide 4 Admin, Backrooms, Cardboard Mansion, and Turret floors
