Template:Incomplete synopsis
While they are helping with the festival, the group encounters Barry again. To test the progress of each other, Ash and Barry immediately start a battle. However, Barry runs off into the forest and comes across a wild Natu. Soon Ash, Dawn and Barry find themselves in trouble facing predicaments that they each faced in the beginning of their journeys. With Dawn and Piplup up against yet another swarm of wild Ariados and Ash and Pikachu up against a flock of wildSpearow, what will be the outcome of all of this?
This is the first episode featuring Barry where his Empoleon does not appear.
This episode reveals that Barry caught his Heracross by slathering honey on a tree.
Interestingly, this episode aired the same week that Stopped in the Name of Love! aired in America. Both episodes had a scene where Dawn & Piplup had to deal with a group of Ariados, which also occured in Following a Maiden's Voyage!, when Dawn and Piplup became friends.
