Sunny’s gaze is drawn to what Need is looking at - majestic horses trotting within the mist - and then the teen instantly sits on the ground, pulling out his notebook. If Need pays attention to her own device at some point, she might see the rough outline of the creatures Sunny is drawing within, though they look a bit stylized compared to the realism of the herd in front of them.

Maybe she wanted something to remember them by? Maybe she was just as awed by them as Sunny felt. (It was still uncommon to see such creatures outside of annual parades in Faraway Town, and even then.)
