Heroes: Latios and Latias
Ross participated in the Tour de Alto Mare, a water chariot race, with his Wailmer, facing several trainers including Ash Ketchum and Misty. Ross and Misty almost finished at the same time but a photo finish revealed that Misty and her Corsola finished first, so she won the race. Ross congratulated her and offered Misty and her friends a tour around Alto Mare.
