Mochi a red florges! it's a very elegant and regal looking pokémon and its dex entries about being kept by governors in castles to maintain the gardens fits her queen of hearts theme (painting the roses red!!) nicely
Hype for Sun & Moon and Pokémon Go have got me in a big Pokémon mood. The rules are simple. Post in character, and then tell the person above you what Pokémon you think would best match their character! You can base this on either looks alone or personality!
For example, let's say the first character posted is Haruka.
Person one: Haruka makes me think of a Woobat!
What about Lulu?
Person two: I think a Sneasel would be a good Pokémon for her! 
Give Jada a go!
Person three: A Meowth would be perfect for her! 
Try Matsuko!
And that's about it. ¯\_(ツ)_/¯
PS, please try not to post an actual Pokémon-related character! It takes the fun out of choosing if you post, like, a Ho-Oh gijinka, because the next person is obviously going to pick Ho-Oh.
PPS if you want to add the little sprites, go here and just type the name of the Pokémon you're looking for at the end of the url. Happy posting!
Creme makes me think of Swirlix! They're cotton candy Pokemon and I think might fit her high energy a little more than it's evolution, Slurpuff (who fits her aesthetic pretty well imho)!
I think Porygon would be good with Shiloh too! Mostly because of the, well, very bright colours! I think Salamence would also fit, because of the colours again and dragon-y sort of theme
I'm not sure why, maybe because she's largely supportive of her friends, but anyways I'm thinking Togekiss!
I feel like Smeargle would make sense; a painting Pokémon plus color manipulation seems like a good duo to me.
