Litwick but instead of a wax candle it's made from the kukui nut, since they're commonly used as candles and such. Prof. Kukui could have one maybe. I don't know what type it would be, though. Fire/Grass maybe?
Still hoping for a mantis shrimp Clauncher/Clawitzer Water/Fire line. Please.
And now that a friend mentioned it to me, Lumineon could use an Alola form since it could be made more colorful/tropical and it could help give it more of a presence, since it's usually forgotten...
Also if the Johto starters got Alola forms, Meganium could have a lei around its neck. In the image with the Alola Exeggutor, there's an old man next to said Exeggutor with a Meganium-patterned shirt. It may not mean much, but I think the Johto starters "fit" Alola well enough to warrant forms. Here's to hoping!
And, as always, Raichu, no Pikachu. Please and thank you.
