Caught the trailer on early minutes of its release.
Thought it was a bit jarring at first from some of the visuals of the pokemon, but quickly felt it was the right way to go about it as the trailer went on.
Caught most of the eastereggs early on. And noticed that it was the same Jigglypuff from the cartoon (it was holding the mic/pen marker) which many missed out on initially. Then had to dig up info on the one in the cartoon and it looks like it's back too in the cartoon since Ep 42 of Sun and Moon series. Anyway, would go and watch, nostalgia will let me give it at least a go.
