The wooden tiger, which the Maharaja had bought for his son on his third birthday, ultimately led to his death in an ironic twist. While playing with the toy, the Maharaja accidentally scratched his finger on a sharp splinter. Though the injury seemed minor, it became infected and worsened over time. Despite medical attention, the infection spread, leading to the Maharaja’s untimely death. Thus, the very symbol of his obsession with tigers, the wooden toy, became the cause of his demise, fulfilling the prophecy in an unexpected and ironic way.
