Jerball

Jerball are some of the most energetic Pokémon in the Carah region. They're loved by some households for their energy, and considered pests by others due to their preponderance. It's unfortunate, however, because the pearls on their tails are often poached and sold illegally, with little to no consequence, and at a great cost to the Pokemon's health. The pearl is believed to have something to do with the sun and moon, but this is yet to be confirmed.
