Kigurumi video.

Cosplay gone wrong I guess, there's an explanation for Kigurumi from Bizarre Japan.

Kigurumi is the Japanese name for costumed animal characters. The name comes from the Japanese term (kiru: to wear) and (kurumu: to be wrapped in). These suited performers are sometimes found at shopping malls, theme parks, and booths at animé conventions. For example, Disneyland costumed characters such as Mickey Mouse and costumed "mascot" characters at sports events would be referred to as kigurumi by the Japanese. Sometimes these characters are to entertain children, sometimes as promotional tactics to grab attention on busy city streets. Full-body animal pajama with hoods or hats styled after animals are also called Kigurumi, but do not have the same "costume" connotation as the full-body suits. They are worn non-commercially and are another form of Japanese street fashion. People who choose to wear kigurumi in public are often referred to as "kigurumin", and the consumer-level costumes they tend to wear are known as "disguise pajama". The suits, which can be bought from several different companies, are made in the style of full-body or semi-full-body pajamas resembling animals or popular characters. The hoods or caps on these pajamas do not cover the face.
