Alright, I don't think Ash or James will get Gulpin. But it looks like a good episode that could lead in to another event.
Correct me on the following if I'm wrong, Murg.
Basically, translating the text on Palette and TVTOKYO, this has been deducted:
Ash and co are on their way to Petalburg City for the Gym badge, when Ash comes across a town (no name). As he enters, Jenny comes by and warns him immediately about the town being terrorized by Gulpins, who are crawling about and eating everything in sight. And Professor Shakuji of this town has been researching the problem and trying to find a way to get rid of the Gulpin. Ash as usual voulenteers to investigate the scene, so Jenny suggests he visit the Professor...
And now, watching the teaser preview, it seems they're using all sorts of mechanisms to try it... and a bunch of grass types as well... a Tangela, a Parasect, and even a MEGANIUM! Heh, maybe from the professor's lab, or possibly a bunch of passing Grass trainers. You'd probably expect Ash and co to try Treecko and Lombre.... well, from the pic alone, it looks like Treecko AND one of the Gulpin are huge and godzilla-like. And no, these are not TR decoy's, they're the deal, as the clip demonstrates it growing.
An interesting fact, according to Palette, in the short teaser summary they have for the ep with Grovyle and Exploud...
At the beginning, Ash is somehow walking in the woods, and his Treecko is STILL in it's huge state (in it's Pokeball, of course). Then they meet some Loudred trainer (yes, Loudred, not Exploud), who overhears Ash talk about problems with Treecko, and tells them he has problems with his Loudred as well. It appears to be rioting constantly, yet the trainer explains it's usually not like that...
Looks fun. Now for my Speculation:
I think that there will be a cool cliffhanger with Ash's Treecko being huge. Yet somehow, the next ep starts with him in the woods. IMO he returned Treecko and ran. Also, I think it's rather safe to say that Treecko evolves, and I know there's no proof... but I mean c'mon. Treecko in an odd state, and all they meet is a Loudred trainer... and the title is EXPLOUD VS GROVYLE. If it doesn't evolve, then they'd have to meet another Grovyle trainer, to battle the Exploud/Loudred trainer. And what do Ash and his Treecko do? Sit and spectate and help again? So yeah, I think it evolves, and when it does, I think THAT's how it returns to it's normal state.
As for the Gulpin ep, I think Treecko and that one big Gulpin managed to drive the rest off, but I'm still wondering what they do with that huge Gulpin, especially since at the beginning of the next one, Ash is still in possesion of Treezilla, and he's back IN THE WOODS again. IMO Ash returns Treecko to it's ball and runs, while the scientist manages to forcefully catch or stop that huge Gulpin and keep it in the lab to study and find a cure to it's normal size... so perhaps, in the following ep, either Ash's Treecko evolves and he calls Shakuji with the news, and then Shakuji helps Gulpin evolve... or vice versa, with Shakuji's Gulpin evolving, and him contacting Ash about Treecko, and Treecko hears this and gets excited about returning to its normal size and evolving.
So that's my speculation... what do you think?
