Carl is the perpetually sullen one, and Mini is the expressionless one. Carl is the outer covering of a pillar with feet called ‘Mini’, and their companions are mass-produced and assigned to various tasks for the Luiio royal family. Carl, the only one with a sad expression on their face, have been assigned to Roy. They don't say a word, only follows Roy's orders, and will be instrumental in getting Roy from Luiio to IDET. As a bonus, they also have the ability to fly like a rocket.
