Abinashbabu

Abinash Chandra Chatterjee (accoding to ??) or Abinash Chandra Majumdar (according to ??) is the next door neighbour of Professor Trilokeshwar Shonku. Although he has very little knowledge about science and foriegn languages (according to Professor Shonku, he knows just three English words) and often makes fun of Professor Shonku's research, he is, by heart a good person. He has even saved Professor Shonku's and his friend Professor Gregory's life in jungles of Africa, in the story Professor Shonku o Gorilla. Later, he saved Professor Shonku's and seven other scientist's lives in the story Swapnodweep.

In the story Aschorjyodweep, Abinashbabu achieved the unique feat of becoming the second (and the only person apart from Professor Shonku) to write in Professor Shonku's diary.

Abinashbabu is a tea lover who drinks three cups of tea every day. The first time he accompanied Prof. Shonku in a scientific expedition was in the story Professor Shonku o Raktamatsya Rahasya, where they along with Japanese scientists Hamakura, Tanaka and Prof. Shonku's pet cat Newton went underwater into the Bay of Bengal from the coasts of Gopalpur to investigate strange red fishes. During this adventure, Abinashbabu collected some rare gold coins which helped him to finance his future adventures.

Abinashbabu is a devout Hindu, and insisted on accompanying Prof. Shonku and his foreign friends to Tibet in the story Ekshringa Abhijan, so that he can have the chance to visit Mount_Kailash and Lake Manasarovar.
