Maybe some headcanons for the alolan kiddos finding a island scan Pokemon? ( I feel like they would be very rare!) and maybe which Pokemon they would find first.. I feel like Hau would find something like a Chickorita first..
-Sun would be the first to do the Island Scan, and would subsequently show everyone else. He found a Luxio on Akala, and was rather surprised. It was after catching it that he gathered everyone else to show them what he did.
-When she went to find it, Moon found a Togekiss on Poni Island. Besides being amazed, after catching it she hopped on its back, and it flew her around the island. It was the best time she’d had in a long time.
-Gladion was the next one, and he only did it after the others coerced him. He found himself a little Spheal. He was amazed. It was so round and happy. He caught it, and now it plays with Silvally every day on the conservation deck. The Spheal rolls, and Silvally imitates. It gets destructive.
-Lillie had to go with Sun and Moon to catch hers. She scanned a Horsea on Melemele, and the three of them decided to swim out to catch him. Besides giving Sun and Moon the biggest heart-throbs at her in a swimsuit, she was able to catch the Horsea with only minor injuries to her psyche.
-Hau was last, mostly because he got all of his QR codes from the malasada shops. He did indeed find a Chikorita, and seeing it made him love the little leaf on its head. Hau’s Raichu is kinda jealous at this, and tries to put its tail on its head now to imitate the grass type.
