The heroes came to Twinleaf Town. To get faster home, Dawn has a race with Piplup. Ash feels as if he is in Pallet Town and see some people. Dawn sees her neighbous, Izzy and Cara. Dawn tells them she is going to be here during the Twinleaf Festival. Cara responds she and Johanna are in charge of setting the festival, but it is all too much work. Dawn introduces Brock and Ash to them, in addition to Pikachu and Piplup. The heroes came to Dawn's home and Dawn impatiently goes in.
Johanna comes and greets them all. Piplup greets Johanna's Glameow and Umbreon, but they do not seem very friendly. Noelle, Johanna's student for Contests, comes, as she reports she has set the rooms. Dawn shows her four Ribbons. Suddenly, Brock comes to flirt, so Croagunk uses Poison Jab and Noelle's Bellossom Stun Spore on him. Ash sees all the Trophies Johanna won. Dawn reminds him she is a Top Coordinator and now passes the knowledge to her students. Dawn challenges her mom to a battle, so Johanna agrees, though she made lunch, so they should go eat first. Johanna asks of Noelle to show them the rooms and Noelle agrees, though she evades Brock's flirting.
Team Rocket is fishing, but they have not caught anything. The man who lent them fishing sticks is angry, as they need the Goldeen for the festival and goes away. Jessie and James remind Meowth they need money or they won't be members of Team Rocket anymore. The heroes eat and they are impressed by the taste. Johanna has heard Brock is a good chef, even she sees Glameow and Umbreon enjoy his food. Brock admits he wants to be a breeder and Johanna has trust in his abilities. Noelle asks of Brock to teach her something about making the Pokémon food, causing Brock to flirt and gets stabbed and sprayed by Bellossom and Croagunk.
Ash contacts Professor Oak (anime) and lets him know they are at Dawn's house. Oak advises him to train, but have fun as well. Dawn and Johanna come to see Oak and Johanna explains Oak will come to attend the Festival. Ash's mom, Delia, appears in good timing to see them all. While she is glad to see her son, she advises Dawn's mom to scold him any when if needed. Team Rocket caught something; James has a Barboach, Meowth a Finneon and Jessie a Whiscash. Jessie is not pleased, as they need to get a Goldeen. Continuing the fishing, they get other fish Pokémon, but do not get Goldeen. Brock helps Johanna by tending the garden, so Johanna thinks she can now have the battle with Dawn.
Cara and Izzy come, with the man who lent Team Rocket fishing sticks, Sayer. They have not decided where and which food to put. Johanna recalls there is some money left and settles the dispute that they can have both stalls placed. Sayer comes again, as they now cannot decide where to put all the food. Johanna goes with them to decide, leaving Dawn disappointed. Ash goes to sightseeing and invites Dawn, but she decides to stay and wait. Ash and Pikachu walk in the forest and spot a boy. He is Nathaniel, who put some honey on a nearby tree. Though not old enough to be a trainer, he still studies to be a one. Ash recalls how he wanted to be a trainer and Nathaniel promises to catch mostly Bug-type Pokémon. Ash tells Nathaniel how he got his Heracross.
Dawn plans her battle against her mom with Piplup and Pachirisu. Pachirisu sees that Dawn's mom got some photos of her. Johanna arrives and soon have the battle. Dawn's Piplup and Pachirisu are against Johanna's Umbreon and Glameow. Piplup uses Whirlpool and Pachirisu combines with Discharge, though Umbreon and Glameow dodge using Quick Attack. They retaliate using Shadow Ball, which hits both Piplup and Pachirisu. Piplup uses BubbleBeam, which creates a wall of bubbles, allowing Pachirisu to hit Umbreon and Glameow using Super Fang. So, Glameow and Umbreon retaliate using Attract, causing both Pokémon to be charmed. With Swift, Umbreon and Glameow defeat Piplup and Pachirisu.
Dawn admits the defeat and still sees how her mom is a Top Coordinator. Nevertheless, Dawn's mom is impressed by her skills and her bond with her Pokémon. Meanwhile, Team Rocket has collected many Goldeen. They go to get a last one, but end up getting blasted off by a Gyarados.
