Dawn and Pachirisu are practicing for the Chocovine Contest, just a day away. Pachirisu's reward for hard work is a delicious Poffin treat, but Dawn's Mamoswine and another Coordinator's Gabite deny Pachirisu even a single bite of Poffin. Pachirisu uses a new move, Super Fang, to attack Gabite for stepping on its Poffin, but doesn't even make a dent. When Ursula, Gabite's Coordinator, comes over to see what the fuss is, she recognizes Dawn as a fellow Wallace Cup competitor—and she hardly thinks Dawn deserved the win!

The next day, the Chocovine Contest begins with Dawn's Buneary displaying its aerial Ice Beam skills. Next, Jessie puts on her Jessilina disguise and shows off her Yanmega. Then it's Ursula's turn, and her Wormadam (Sandy Cloak) takes the Contest by Sandstorm. All three make it to the second round and begin to battle their way to the top, where Ursula and Gabite defeat Jessie and Carnivine. That sets the stage for a final round battle between Ursula and Dawn, and even Dawn's disobedient Mamoswine starts paying attention to the action.

Ursula's Gabite is up against Dawn's Pachirisu, and Pachirisu's spinning dodges or Super Fang attack don't affect Gabite one bit. Things look bad for Pachirisu, but Dawn keeps her cool and leads Pachirisu to a comeback. First it counters Gabite's Stone Edge with Discharge, then uses its tail to block Gabite's Dragon Claw. As Pachirisu spins into a Super Fang attack, time is called: Dawn and Pachirisu win! Even Mamoswine is just a little bit impressed. Now that Dawn has won her fourth Contest, our heroes are off to Snowpoint City for Ash's Gym battle.
