With a crunching sound, Sir Sweetie Von Zauberer-Dorn Wunderbelle, legendary and daring explorer, stepped foot on the top of the mountain. From this soaring peak, she raised her trusted binoculars to her eagle eyes, peering across the horizon for what treasures lay beyond it.

"Look, my faithful companion! North of this mountain lies a great waterfall! Adventure awaits us there!"

Rarity raised her hand to her face, shielding her eyes from the sun as she squinted at where the plastic binoculars were pointed.

"I think those are the drinking fountains, sweetheart."

Sweetie snorted at this, turning to the older unicorn with a glare. "Well there can still be adventure there!" "she half-whined.

"I'm sure there can be." Rarity giggled. "Now, would you like some lunch before setting off on this grand adventure? I used strawberry jelly!"

At the mention of the absolute most bestest thing you could ever put on a peanut-butter sandwich (or any sandwich, as far as she was concerned), Sweetie leapt off the rock and sprinted to the picnic table, nearly dropping her prized toy. An adventurer should never go off on an empty stomach, should they? Not when such a delicacy as this was offered! Besides, this park probably wasn't TOO explored yet. She'd make her mark long before anyone else could beat her to it.

It's been a very, very, very long time since the Marshmallow Sisters showed up, hasn't it? Well fortunately that has now been fixed. I'm going to say this isn't that long after Sweetie moved in with Rarity, only a few months in. She's settling in nicely, as you can see.

Silly Sweetie, one day you'll realize grape jelly is infinitely superior.
