I just noticed something after re-watching episode SM020, the Pokemon images on the souvenirs have the Pokemon GO artworks used in. That also includes a Porygon here, the banned Pokemon from the original series episode. What a surprise seeing it as a souvenir image, isn’t it?
I wonder if the recent baseball episode in Sun & Moon was actually referencing the original series with that Electabuzz at the beginning, just like Casey’s favorite team.
Also I remember Ash mentioning that the Electabuzzes always lose to The Starmies and The Magikarps. Isn’t that the same name as the team from the guy that taught Ash and his friends baseball in this new episode?
