Gonsuke

ゴンスケ

Gonsuke, known as Gaozook in the English dub, is a robot that typically plants and harvests sweet potatoes. He originates from Fujiko F. Fujio's manga, 21-emon and Ume Boshi Denka. He also appeared in several special episodes of the 2005 Doraemon anime, serving as a policeman, a car mechanic, and in other roles.
In the 2002 film, he merely digs one large hole in the Open Lot and asks Doraemon if he can assist. Conversely, in the manga, he and the Mole Robots dig multiple holes in the lot and have Doraemon removed by police robots.
He also appears in the ongoing 2005 anime series as a large-sized robot. Even a Transformer-style head can be attached to him.
