In He'll Be Comin' Down the Mountain, he arrives in Penguin Village with his grandson Ryota to visit Senbei which took him two years from a ox drawn carriage. He and Ryota get introduced to every day modern technology and Senbei's new wife Midori. In He'll Be Goin' Up the Mountain, he reveals that Arale being Senbei's sister is a lie to Midori and then leaves at the end of the chapter with Ryota.
- His name is revealed as Jubei in episode 22 of Dr. Slump Arale-chan.
- His first appearance in the anime has a massive inconsistency as he is seen driving a car but when he actually first appears in the manga, he isn't familiar with it or any kinds of technology.
