A costumed performer or suit performer wears a costume that usually, (but not always) covers the performer's face, typically to represent a non-human character such as a mascot or cartoon character. These range from theme park "walk-around" or "meetable" characters, the mascots of corporations, schools, or sports teams to novelty act performers. Some costumes cover the performer's face especially those in theme parks. Examples include sports mascots and performances as fantasy characters on children's television and in theme parks. Problems in suit performance include intense physical exertion, claustrophobia and hyperthermia. In theme parks, international fairs, and festivals Costumed performers are a major feature of amusement parks like Walt Disney Parks and Resorts, Universal Parks & Resorts, Sesame Place, Legoland, SeaWorld, Hershey Park, Six Flags, and Nickelodeon Universe, as well as many other large or small theme parks and fairs. Costumed performers are intended to add to the fantasy experience by enabling visitors to encounter and interact with fictional characters, such as mascots for a company or organization. The characters are portrayed by employees in costume. Some of the costumes merely consist of clothing and makeup, while those for non-human characters generally conceal the performer entirely and include a full bodysuit, a head, and sometimes accessories or clothing on top of that. A longstanding policy in most well known theme parks is that the first category of characters, where the performer's face remains visible (usually "face" characters) are allowed to speak (usually on the basis of scripts carefully prepared in advance), while the second category of characters, where the face is covered (sometimes called "fur" characters) are not allowed to speak, although are allowed to make noises, and tend to communicate through pantomime. A common occurrence, often involving "fur" characters, is that young children can feel particularly intimidated by the size of the costume. They can also be intimidated by the quick movements of more energetic characters, or by the character approaching them directly, so performers frequently slow down or kneel down when interacting with smaller children to let the child approach them. For human characters based on a well-known media franchise that speak with visitors, theme park operators may prepare detailed scripts covering a variety of questions regularly asked by visitors, especially young children who have difficulty distinguishing between reality and fantasy. Performers cast in those roles are required to memorize and rehearse those scripts as part of their training,
