This episode wasn't too bad. It's sad that there's only one more episode to follow in the DP series, but it's been a great ride; without a word to perfectly describe.
Anyways, I'm glad Brock got this episode dedicated to him solely, and having to help the baby/mini Pokemon. Baby Pokemon have always been a favorite of mine, likewise. :P
What I also liked about this episode was the many anime showings of Items you see in the games. Such as the few berries shown, plus the Lava Cookie from the kind old woman. Not sure if I saw one before in the anime, but it's still great to see Items, as well in, the anime.
It was saddening to see Pichu's fever was taking so long to recover, but I'm happy to see everything would work out in the end. Of course. But I'm surprised that Brock's Happiny evolves here, to help recover Pichu's fever. Though, I'm somewhat satisfied; considering Brock's team has been updated since Season 10.
Overall, good episode for Brock; but not a too bad episode overall. And now for the finale of DP next week. Things will surely grow exciting for what's to come afterwards.
