Moonstuck

You’re waiting for EXACTLY SQUAT, that’s what! In record time, you whip out your -.75 Prescription Goggles and reassemble your headgear into the Cartographer’s Bathing Cap.
Then you set out through the hole at a brisk front crawl, grateful for the rigorous training and exercises you underwent as Equestria’s Most Adorable Swimming Champion.

Hey, is that a light up ahead?

Success! A small portion of the wall crumbles away, creating a Woona-sized hole just large enough for you to swim through.

You take a deep breath and muster up your cutest, most pleading face.

The wall remains unmoved.

The wall says nothing back.

It doesn’t seem very friendly…
