Arnold reunites with his mother.
Arnold (Japanese: ハジメ Hajime) is a character of the day from the episode Hypno's Naptime. He is voiced by Kayzie Rogers in English and 西村ちなみ Chinami Nishimura in Japanese. He is a doppelgänger of Ash and Travis. His only difference between them is Arnold's hair.
He was one of the children that became hypnotized by Hypno's sleep waves, resulting in him becoming lost at the park. Luckily, Drowzee's dream waves were able to wake him and the other children up. At the end of the episode, he was reunited with his mom.
Arnold likes Pokémon but has not expressed an interest in becoming a Pokémon Trainer.
