In #MonsterHunterWorld these creatures are called "pearlspring macaque" and some of them are in DLC city centre. Around various holidays, where everything is decorated, they also have seasonal costumes. During one #festival they look like this.
Cartoon style drawing of a gray fluffy creature, partially similar to small monkey, partially to teddy bear. It is wearing costume made of giant orange and red feathers/leaves. It looks similar to peacock tail, spread around its body in front view. The creature has also small flower-like decoration on its head. Orange feathers are well visible on blurry gray background.
