 Tintin in the Congo shows Tintin taking part in what Michael Farr described as " the wholesale and <unk> slaughter " of animals ; over the course of the Adventure , Tintin shoots several antelope , kills an <unk> to wear its skin , rams a rifle vertically into a crocodile 's open mouth , <unk> an elephant for ivory , stones a buffalo , and ( in earlier editions ) drills a hole into a rhinoceros before planting dynamite in its body , blowing it up from the inside . Such scenes reflect the popularity of big @-@ game hunting among whites and affluent visitors in Sub @-@ Saharan Africa during the 1930s . Hergé later felt guilty about his portrayal of animals in Tintin in the Congo and became an opponent of blood sports ; when he wrote Cigars of the Pharaoh ( 1934 ) , he had Tintin befriend a herd of <unk> living in the Indian jungle .
