"Carkol, the Coal Pokémon. It forms coal inside its body. Coal dropped by this Pokémon once helped fuel the lives of people in the Galar region." – Pokédex entry for Carkol.
"For some reason, I really want a Carkol." Shuichi remarked to no one in particular. "Don't you think they look cool? With how they roll around on their legs, getting around must be easy for them. And who wouldn't want a portable source of heat wherever they go? They're the perfect Pokémon for travellers like us."
"No one asked you for your opinion, Shuichi." Kumiko barbed back, unsure why Shuichi was suddenly talking to her about a Pokémon he would like to have. "The last time I met a Carkol, it was when I fought Subdomi City's Gym Leader. It moved so fast I had trouble keeping up with it!"
"Maybe I should get a Carkol just for the sole purpose of defeating you." Shuichi mused, causing Kumiko to glare daggers at him. "Since you always beat me in fights, it's about high time I give you some well-deserved payback!"
