After Sean's Father's Blitzle and Sean's Father's Patrat were too tired to battle, Sean went back to his dad and borrowed Sean's Father's Scolipede and Sean's Father's Seismitoad so he and his friends could continue battling. Glenn commanded both of the Pokémon in a double battle against Pikachu and Ash's Krokorok.

Sean attempted to help out by giving Glenn advice by specifically telling him to match up Sean's Father's Seismitoad against Pikachu because of the type advantage but Glenn wouldn't take the advice. The inexperience of Glenn and his unwillingness to accept advice proved to be the reasons that Sean's Father's Scolipede and Sean's Father's Seismitoad lost the battle. After the battle, both of the Pokémon were given a blend of Berries and medicinal plants from Cilan in order to recover.
