This was a filler of a filler. Literally one of the biggest fillers ever. AND I LOVED IT! This episode was almost everything I thought it would be. There sure were lots of Water Pokemon and I was certainly not expecting to see the Piplup species here. I thought for sure Piplup would be saved for a DP remake 20 years from now. But seeing Bonnie interact with one was so cute. I never had a problem with Piplup unlike half this forum.
The episode itself was enjoyable. Almost everything was great. The old fisherman and his Clauncher were entertaining characters. Old men in Pokemon are generally entertaining for me. Clemont delivers like he always does and he made not one but two devices. I loved how that Sharpedo swarm destroyed his first one and for good measure the remote blows up in Clemont's face. Bonnie once again demonstrates why she's such a good fit to the episode. Her small subplot with trying to bond with Clauncher was cute. She was determined to win the king of crab...lobster Pokemon over. That is Bonnie's quest. To befriend and play with every Pokemon she sees, and she was great for me in this episode.
While Bonnie was great today, she was not the show stealer. I cannot believe I'm saying this but after 21 or 22 long episodes Serena takes home the show stealer trophy. The writers finally made good use of Serena. She didn't even do that much, but you don't always have to for this anime to stick out, at least for me. Serena being nervous on how to fish, having to be taught how to fish by Ash and Clemont, and finally trying to catch a Pokemon made this episode. Nothing compares to it IMO. I don't even care that she failed to catch her Pokemon, or that it was Corsola of all things. Serena finally looked like a real Pokemon trainer. A rookie one, and that was today's show stealer. Divakin was used perfectly. I'm glad it didn't fight. Probably didn't want to get dirty and hides behind her trainer so she takes the hit. That was good! I want to see more of this relationship. I just hope they don't become Ash and Pikachu 3.0, it's what killed Dawn and Piplup.
The music was also great. They played the Gym Leader music when Serena's attempting to have Divakin catch Corsola and the Kalos Legendary theme for when they saw the gold Magikarp that only got a 3 second cameo in the episode. This was a good episode. Everyone was used well here, even Team Rocket as the plot device for Bonnie and Dedenne to make friends with Clauncher. Good solid filler episode. I enjoyed it. Probably one of my favorite Kalos episodes. Keep doing episodes like this. And what is up with these random Thunderbolting Starmies?
And no Cyber, I am not surprised that Serena didn't ask about Dawn. Nor do I care. She has zero importance here.
Parena or Serecham both equal Serena+Pancham! Sereevee or Serevee equals Serena+Eevee!
