Dawn then comments that regardless, all three Pokémon would make a great partner in her bid to become a top just like her mother. In her younger years, Dawn's mother had earned many certificates and trophies, which inspire Dawn. She begins fantasizing about performing in s with the three different Pokémon, acting out all her actions while her mother watches on.

She arrives in a town, and runs into a building which she believes to be the Professor's lab, only to find that it is a restaurant.

The gust breaks a window in the lab, allowing the two birds to fly through an open window, followed by Chimchar (with Piplup in hot pursuit).

With only the Turtwig remaining, after getting glared at by Rowan, continues to eat its food, Dawn asks and is allowed to go and search for the four missing Pokémon. After receiving some tips from Prof. Rowan, Dawn runs off towards the forest where the Pokémon were headed. Before she reaches the forest, however, she runs into Chimchar and Piplup, Chimchar still swinging away from Piplup's. Dawn attempts to calm them down, but they ignore her, Piplup changing its target to her briefly before both disappear into the forest. Dawn runs into the forest after them, only to hear Piplup's cry. She runs toward it, seeing Piplup as well as several other Pokémon trapped in a web created by an. The Ariados notices Dawn, chasing her through the forest.

Despite being disdainful earlier, Piplup accepts the food. She then spots Staraptor carrying Chimchar back to the lab, with Starly close behind. Before they can return to the lab, however, the lake ripples, and a mysterious figure appears for a moment before vanishing. Upon returning to the lab, Dawn asks Professor Rowan about the figure.
