At the time that Corbel was created, I was still playing Freddie in the Pathfinder game he was in. Freddie was an elf until he got mind-swapped with his familiar by psionics, effectively turning him into a frog irreversibly. So the people I play TTRPGs with got the concept of a tiny wizard who spends most of his time on another party member's shoulder and fires off spells from there, but just how tiny a Minish is could use illustration!
