(Choose a pre-evolution or middle stage evolution pokemon)

You were summoned by King Pikachu to the throne room and quickly made your way there. Upon entering, you saw the king lounging on his throne, his legs crossed and his head resting in his hand. He observed you intently before speaking.

"Since you haven't fully evolved yet," he began, his tone matter-of-fact, "I shall put you in diapers to lower the chances of any of my servants who are still in their pre-evolutionary stages from having any accidents."
