You seemed to have entered a town called “Big Town” in the Pokémon world. The first ones to greet you were 2 Pichus. The older one had a small tuft of hair on his head, while the younger one was bald. They seemed to be saying “Pichu” constantly, but luckily for you, you had a translator so you could translate what they were saying.

Pichu Little: Hey! Welcome to Big Town! Pichu Big: What brings you here?
