The Hitcher' appearance changes somewhat between appearances. In the first series episode "The Hitcher" he has an abnormally large thumb, as well as nose and chin. He explains his huge thumb as stemming from his visiting a Hornet Shaman in the bin of a primary school and asking him to enlarge his thumb by stinging it repeatedly. In the second series his thumb is normally sized. In the third series he has a normal chin and nose. As he melted at the end of prior appearance while washing in the Fountain of Youth, this last change of appearance could stem from being de-aged.
