Professor Oak's Backyard, deep in Back Mountain.
After saying goodbye to the Kangaskhan population, they continued their search for Popplio.
Ash asked, "Pikachu, can you pick up Popplio's and Marowak's scents?"
"Pika!" Pikachu twitched his nose, trying hard to distinguish the mingled scents in the air.
As they searched carefully, a somewhat unusual-looking "Kangaskhan" poked its head out from behind a tree.

"Come on, Arcanine's found them!"
With Arcanine leading the way,
they finally found Marowak and Popplio. Marowak was still fearlessly challenging Onix, oblivious to the danger...
"This guy's got way too much courage!"
"Awooo~"
After Kiawe picked up Marowak and brought
