Except of course Goh potentially catching a Diglet to make up for his failed attempt in episode 6 and maybe he learned not use his hands to try to catch it this time.Doesn't matter the summary is delayed. It's not like something very interesting is happening in this episode!
There's two episodes. One in Kanto with the first phrase and the other in Kalos in the episode with the shiny phantump.I remember watching an episode where a lot of Diglett and Dugtrio were doing a sound like this, I only watched it once and I don't even remember what that episode is about, but I still remember the sound XD
How much do you want to bet it's Team Rocket either trying to steal pokemon or pull off one of their get rich schemes?Endo writes that he's been having trouble recently due to Digda and Dugtrio ravaging his field, so Satoshi, Go and Koharu head to Endo's field to investigate and find out why these Pokémon are doing this.
