Watching this episode in Japanese is a waste of time for me.
An average idoit like me won't know what they're doing or saying.
The only thing that stood out to me was sudo using Hammer Arm, Signal Beam's animation and that Galactic sticker(because stickers are cool. Not)
I don't even understand Happiny's immense strength. Nothing in it's pokedex entries state anything about it. It looks like it's just thrown into the anime for fun. Gah.
