We really need the Spoiler forum back =(
Yup, you probably guessed it.
Translated from the TVTOKYO blurb:
Lombre and Solrock! Legend of the Forest!
Ash and co are headed through the woods towards Petalburg City, ready to get to the next Gym. Eventually, they make a pit stop in a village in the woods. As they let out all their Pokemon in a nearby park, suddenly Brock's Lotad evolves into a Lombre! Just then, as soon as the villagers notice Lombre, they seem really happy, and start to beg. Ash and co later find out that this village has been really poor and dry lately, and really low on water. Therefore, all the villagers are praying for rain from Lombre. They haven't had a decent source of natural water in a while, and the village is in danger. Luckily, Lombre gives them a fair share of Rain, but for some reason it's not as successful as it's supposed to be. Then they ask one of the villagers for more information, and he tells them that they've had this drought problem ever since a Solrock appeared in the woods...
Yeah, I bet you can guess what this is about. Rain Dance VS Sunny Day. Heh, now the question is, what'll happen to Solrock? Will it make peace with the village? Will they defeat it and have someone capture it? :o
Time will tell.
Also, for some reason the clip isn't there YET. They're a bit laggy as they've been the past few weeks. I'm sure it'll be up in a few hours, but right now they have the one of last week.
