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 its companions are mass-produced and assigned to various tasks for the Luiio royal family. Carl, the only one with a sad expression on its face, has been assigned to Roy. It doesn't say a word, only follows Roy's orders, and will be instrumental in getting Roy from Luiio to IDET. As a bonus, it also has the ability to fly like a rocket.
