In Part Two of R. K. Narayan's novel The Painter of Signs, Raman and Daisy visit a remote village, after which they return to Malgudi. Due to unforeseen circumstances, they need to spend a night on the road, Daisy sleeping in a bullock cart and Raman sleeping under it. The next morning, Raman discovers that Daisy spent much of the night in a tree:
Then he asked suddenly, 'When did you learn tree climbing?'
'We used to play Gorilla when I was young; whoever becomes a Gorilla must climb a tree and stay there. We used to play this for hours day after day, and that's been helpful. (...)'
Is this based on a real game or did Narayan make this up? If it is a real game, what were or are the rules? If multiple versions of this game exist (or existed) in India, I am most interested in a or the version played in the state of Tamil Nadu, from which Narayan originated.
