Noticed you commented this twice so I'll reply. Happy for you that you got to see it. Not sure if it was my actual first but Garnet was one of them, and it was nice to see Hocen do that so I can imagine how nice this is to see.
I'm very outdated on Pokemon (only remember the first couple gens) so I'm no sure if that's to represent a water attack, but the bubbles are a nice background touch here.
