      Hi! Thank you for your question :)
      Noctis needs to sneak behind the Black Chocobo until Ignis distracts it. The player should keep the chocobo inside his field of view to see if it is looking around, if so, Noctis needs to duck (hold square). Keep on doing this while also moving towards the chocobo until Ignis distracts it. While it is distracted, pick up the glasses then run away before the timer ends.
