KBTR is a graffiti-character mostly seen on the streets and from a train window. He is known for his red hat and his personality with a lot of different appearances and expressions. He is also nicknamed 'De Utrechtse Kabouter' after the city Utrecht where he first appeared and still can be seen the most. He also appears everywhere around, so in that case the name (KaBouTeR) after the suspected makers is more fitting.
