Gloomy Bear Costume
Balance cute and creepy with this iconic pink, blood-stained bear look.
Created by Japanese artist Mori Chack, Gloomy Bear is a deceptively cute pink bear who frequently attacks his owner. This costume is incredibly popular for conventions and Halloween because it perfectly balances kawaii pastel aesthetics with a dark, bloody twist. The signature look relies on a bright pink bear silhouette complete with sharp white claws and fresh blood splatters.

How to put it together
- 1
Put on the pink Gloomy Bear kigurumi or your DIY pink sweatsuit base.
- 2
If DIYing, attach the white felt muzzle and pink-and-white ears to the hood using fabric glue or safety pins.
- 3
Apply red fabric paint to the muzzle area of the hood, creating dripping blood patterns around the mouth.
- 4
Paint the tips of your white plush claws with the red fabric paint to look like fresh blood.
- 5
Let all painted elements dry completely before putting them on.
- 6
Put on the plush claw mittens and pull the hood up over your head to complete the silhouette.
Makeup & hair
Keep hair simple or tucked into the hood. For makeup, apply a pale foundation, a touch of pink blush on the cheeks for a kawaii look, and use red face paint or fake blood dripping from the corner of your mouth.

Gloomy Bear costume FAQ
- What is the official brand for the Gloomy Bear costume?
- The official, licensed Gloomy Bear onesie is made by the Japanese brand SAZAC, known for high-quality fleece kigurumis.
- How do I make the blood look realistic on the fabric?
- Use a dark red 'slick' or 'gloss' fabric paint. Apply it in thick drips and let it dry without flattening it to maintain a 3D, wet appearance.
- Is Gloomy Bear suitable for school or family events?
- Because of the blood theme, it might be too graphic for some school dress codes. You can make a 'clean' version by omitting the red paint entirely.
Did you know? Gloomy Bear was created in 2000 by Mori Chack as a reaction against overly sweet, sanitized mascot characters like Hello Kitty, highlighting the wild nature of real animals.
