Iro looks just like every other Cappy in the show with his yellow pear-shaped body with rosy cheeks. He wears a little straw hat with a blue ribbon and a blue and light yellow shirt split in two. He is the tallest and the oldest member of the trio of child Cappies.
As a friend of Tuff, he is a young juvenile who enjoys pulling pranks and causing trouble for other Cappies. Although he sees himself as a cool person, he can be quite immature and temperamental at times; if things don't go his way, he usually whines or throws a temper tantrum (as seen in Dedede's Raw Deal). In earlier episodes, Iro acted a bit like a bully around Kirby but eventually they became friends.
That kid was scared 'cause he knew the wolf blew down the pig's house and gobbled up Red Riding Hood's grandma.”
