Once upon a time, a lion was sleeping under a banyan tree at the roadside/by the side of the road/ alongside the road. An ant was going (walking) through the same path (road). She accidentally/mistakenly went over/upon/on the lion. On his sleep being disturbed, the lion woke up roaring loud (in/with a loud roar). He yelled/shouted at the ant “How dare you bother me?” The ant started shivering/trembling (began to shiver/tremble) with the fear of death.
