Sabu decided to stay on Earth with Chacha when he tasted delicious paratha and halwa made by Chachi during his visit to earth. Both Chacha and Chachi treat Sabu like their own son and in certain stories Chachi is shown to have more affection for Sabu than even Chacha Chaudhary. Sabu has a twin brother called Dabu and the giant earrings that Sabu wears were gifted to him by his mother when he left Jupiter. According to the comics, whenever Sabu gets angry, a volcano erupts at some distant place (this is stated in a panel with a picture of a volcano erupting, which says, "When Sabu is Angry, a Volcano Erupts at some distant place in Jupiter"). Whenever he performs an act of great strength, he utters the cry, ""Hu-Huba!"". Sometimes he has been found to utter "Jai Bajrang Bali" which roughly translates to "Hail Hanuman" (a popular Hindu God). It is revealed in some comics that and Sabu eats 202 chapatis, 14 kilos of halwa, 22 kilos of rice / pulao, 7 kilos of vegetable preparations, 10 kilos curry, and about 18 litres of lassi (the favourite part of his meal) in one meal. He often finishes the meal with a basketful of fruit. He is often served lassi, tea, juice or some other non-alcoholic drink in a large bucket or pot. He is not married, and avoids the topic.
