You tell the unicorn that you hope she doesn't mind you invading on her shower like that.

Unicorn: "Nah, it's okay. Besides, you both looked like you really needed one! Where's the lucky guy, anyway?"

You tell her that it's actually just the two of you.

Unicorn: "What? You can't fool me, cream-filled cookie."

Moonflower: "Heehee! It's true! We used a super special magic ring to turn me into a boy."

Unicorn: "A magic ring, you say? Well, now I'm intrigued... Oh, by the way, I'm Sweet Biscuit."

You introduce yourself to Sweet Biscuit.

Moonflower: "And I'm Moonflower!"

Sweet Biscuit: "Nice to meet you both."

Sweet Biscuit gives herself the once-over.

Sweet Biscuit: "Hmm... good enough. I was just getting ready to play some Temples and Titans with a couple of friends, back at our room. I'm thinking we could use a few more players, though. Interested?"
