Mythical-Moonlight
I just ran, I ran all Night and Day ~
I'm conflicted. Grookey's a fun Pokemon and I really like it's dynamic with Pikachu and EeveeI homnestly don't want Grookey to evolve. Thwackey is ugly and and I love Grookey's "loveable rascal" personality too much to want to see it inevitably become a stoic and mature (AKA boring) Rillaboom. Unless they decide to have it behave like an internet troll in a similar vein to Darmanitan ... that might actually be fun!
But on the other hand Rillaboom deserves attention too.
I just hope it retains it's personality like Cinderace did
