From WiKirby, your independent source of Kirby knowledge.
Horror Tramp is a ghostly enemy that debuted in Kirby: Triple Deluxe, first encountered in the Lollipop Land level. It yields no Copy Ability if swallowed.
Horror Tramp looks somewhat like a ghostly version of Waddle Dee, but it has a much creepier face with only one eye and a gaping mouth. It raises its arms up in a stereotypical monster manner when it runs after Kirby. Horror Tramp will usually poof onto the scene from the air before attacking, and if encountered in rooms with mirrors, it will be invisible unless viewed through said mirror.
