> Test the bravest warriors bravery

> Perhaps one of the batponies would be willing to disguise themselves as you while you slip away safely?

You proceed to explain Operation: Changeling to the bat ponies:

Decoys will be simultaneously released at points twelve o’clock and three o’clock, to draw and hold the attention of your diabolical doppelgänger. They are not to engage the target, but rather to lead her a merry chase while you sneak away unseen.

Once the filly realizes you’ve escaped, you feel certain that she will give chase, leaving the colony undisturbed and able to come and go as they please. Win-win!

The leader agrees to attempt your plan, and in recognition of your service to the colony, offers you the use of her bravest warriors.

> Forget ancient treasure, there’s more adorable dressing up to do!

Wait…this dress-up game has sparked the beginnings of a cunning plan in the depths of your incredible strategist’s mind.

Nopony can leave the cave, because of the evil filly and her rockslides.
But the evil filly seems to be after you specifically, for some mysterious diabolic reason. Maybe there’s some way you could distract her long enough to sneak away…

> Well, are there any old ruins and buildings that she might know of?

As you engage in a game of fancy dress-up, she admits that the only such structure she knows of is the Mysterious Moon Maze that you passed through on your way here.
Supposedly it holds an ancient treasure; perhaps it could be what you seek?

Of course, to return to the maze, you’ll have to get out of the cave…

> The leader is within your reach! Quick, boop her on the nose before you miss your chance!
