A young trainer in a red cap and blue vest, with a yellow mouse-like creature on his shoulder, throws a red and white spherical device toward a large, plant-like creature with a wide mouth, which is hanging from a tree branch; the device expands and closes around the creature, which is then shown underwater surrounded by bubbles, before the scene cuts to the trainer and his creature standing together in a grassy area with trees and a blue sky.
