On this episode, Ash and his gang starts going to sleep. Later, Pikachu and Meowth unexpectedly goes on a dream adventure.
I've been watching this season for quite a while since the first episode released but haven't mentioned about it until now. Anyway, I wanted to point out this episode specifically because there's other talking Pokemon which basically reminds me of my favorite Pokemon Mystery Dungeon series (plus I've been playing Pokemon Super Mystery Dungeon and passed the main story a while back).
Also another Pikachu's solo adventure was just plain cute and cool to watch. Other than that, there were some really hilarious scenes. Now what's going to be Ash and Pikachu's next adventure? Overall, an awesome dream adventure for Pikachu.
Conclusion: An awesome dream adventure for Pikachu.
