Our heroes have contacted Prof. Oak to give him an update on recent happenings, when Oak brings up the fact that they’re in Canalave City. He says that because of this they should check out the nearby Old Chateau, where they can find-make Old Gateau, which he says is quite delicious. Team Rocket, of course, was eavesdropping on the whole conversation, so they decide to go to the Old Chateau to swipe all of the Old Gateau before Ash and comp. can get there. Little to any of them know, however, that "haunted" appliances await... Pretty good episode; a fitting start to Pokemon’s 12th season, and while there wasn’t really any heart-pounding action, there were some lol’s in seeing Rotom take on all of its different formes and chase Ash and comp, and Team Rocket, all over the place. As for the new opening theme, I think it’s great, and the song is awesome. The main thing I don’t like about it, however, is when Ash’s Pokemon say their names at the end of it; that kinda puts a downer on the song’s ending, IMO. It also would’ve been nice if some scenes from "High Touch" (the Japanese opening theme) were used, too. But overall, I still think that it’s the best opening theme so far in the Sinnoh Saga.

Ash and friends are in the Pokemon Center watching a show about contests. Ash decides to go and train for his gym battle.

On the way to Snowpoint City, Ash and friends stop in a town where they meet a girl named Marylin who only likes cute Pokemon. After she insults Dawn’s Piplup, Dawn challenges her to a battle, but Marylin is more concerned by how "cute" and "valiant" her Pokemon act in battle rather than whether they win or lose, or even get hurt. Brock gets upset by this, so not long after the battle is over, he challenges Marylin to a battle himself to try to show her that it’s the bond between Pokemon and Trainer that really counts.

Upon finally arriving in Snowpoint City, Ash and friends meet up with Zoey, who welcomes them to her hometown.

This new arrival gets Paul’s blood boiling, as he knows that Brandon is the one that Reggie lost to, and the person that caused him to give up as a trainer.
