Gonsuke

Gonsuke, or Gaozook in the English dub, is a robot that generally plants sweet potatoes and harvests them. He is originally a character from the Fujiko F. Fujio's manga, 21-emon and Ume Boshi Denka. He also appeared in some Doraemon's special episodes (2005 anime) as a policeman, car fixer and more.

In the 2002 movie, he only digs the single large hole in the Open Lot and asks Doraemon if he may help him. However, in the manga, he and the Mole Robots are digging several holes in the lot and get rid of Doraemon by the police robots.

He also appeared in a current 2005 anime series as a big-sized robot. Even the Transformer head can be applied as his head.
