Yeah i'm personally more into the original plushies' stripes than actual mocha swirls!

I think at one point someone brought up the subject of 'transformable' colors in another pet color thread or something, and I think this could relate well. I feel like Gingerbread could be a transformable color during Luminaire! As in, you start by coloring your pet sweetheart, and then only during Luminaire (or even only on the day itself) can you have the option to complete a task and turn your pet Gingerbread (like how you gather crystals for galactic). Maybe something like on Luminaire you have to feed your pet a few gingerbread items that Melody randomly selects? Then it's also getting sP and items out of the economy on top of the cost of the original sweetheart potion. It adds another layer of player/game involvement, without having to create an entirely new potion.

Maybe Peppermint could be another transformable option of sweetheart as well for Luminaire? Like all of the adorable Chibi Peppermint plushies:

I did some gingerbread mockups! (drag for full size)

Love this; I like the gingerbread, but I personally like mocha more. If we get either of these, I'd change my baker pet to it as soon as I could manage :3

As for how we'd get it..the Gingerbread would probably be something we could 'bake' in the bakery during Luminaire..like Fantine finds some old recipe in some old book and wants to try it, but she needs help with it in some way and some Lumi magic winds up in the final product and turns it into a potion. If it was Mocha: Jade tries to make a new coffee drink and somehow winds up with a potion.
