Napper

"Grunty's gold how it shone, she'll be mad now it's gone!"

- Napper Napper is a large, green ghost that appears in Mad Monster Mansion in Banjo-Kazooie. He is specifically located in the mansion's Dining Room, and was entrusted by Gruntilda to safeguard a Jiggy from Banjo and Kazooie.

Napper is transparent while he is asleep, but becomes more opaque while he is awake. Napper is a light sleeper as even slight floorboard creak awakens him. Because of this, Banjo and Kazooie must take an alternate route into the mansion by entering from a chimney on its roof. After this, they must hop from the fireplace to the chairs positioned in front of Napper and onto the table, where they must walk through Napper to obtain its Jiggy. By doing so, Napper wakes up and flees in fear of Gruntilda's wrath.

Trivia

 * According to Grant Kirkhope, his voice is a slower variant of Banjo's voice.
