A little drabble about Finn and Princess Bubblegum in a picnic that brings big revelations to them -One shot-

Six years after she took over the kingdom, Flame Princess's heart is dying; its energy is fading away. There's only one chance to save her: traveling into a dangerous and merciless land. Finn offers himself to this task as the hero he is. But, what if a hero is not enough for this task? And what happens when, at the same time, the land of Ooo faces a powerful danger?

One-Shot. It's good to have friends in the hardest times (Don't read if you haven't watched Wake Up and Escape From The Citadel)
