It's not a glitch. It's a representation of the large void in our hearts that comes from the never-ending greed by stealing from chests in the forest. The world is trying to convince us to change our moral values and give rather than take, to explore rather than conquer, to swim rather than sneak. I think we should all learn a lesson from this gift: a sentient world that understands life's deeper meaning and seeks to aid us in our quest of enlightenment and wisdom needed to win the Survival Games.
