Pokémon S10E1 - Following A Maiden's Voyage!

It's always exciting when new Pokémon Trainers receives their first Pokémon, but for a girl named Dawn, things will be far more exciting than she'd ever imagined! Here in the Sinnoh region, Trainers receive their Pokémon from Professor Rowan, whose lab is near Sandgem Town—but soon after Dawn leaves her home in Twinleaf Town and heads for the lab, she's hopelessly lost. Fortunately, she runs into Professor Rowan on the street and follows him to the lab. But while the Professor was out, his assistants accidentally let two of the starter Pokémon, Chimchar and Pilplup, break out of the lab.
