You make your way to Moonflower, and show her the seashell you found underwater.

Moonflower: "Oh, cool! I'm not sure what they're for, but I think I saw somepony collectin' those 'round here. Maybe it's valuable!"

You ask Moonflower what she would like to do next.

Moonflower: "I dunno! I don't wanna go swimmin' with my hat on, in case I lose it, but I can't take it off 'cause it's too sunny. Hmm..."

Sweet Biscuit: "Trailblazer, Moonflower! How about a game of volleyball against Swirly and I?"

Moonflower: "Ooh, that sounds fun! What'cha think?"
