He was an ordinary cockroach until he started growing. At first it was the size of a cup, then the size of a saucepan, and then became the size of a man. His forelimbs can grab things. He's like a man in a cockroach's shell. Smart and kind, knows how to talk and wants to find a friend. The old man who lived in this apartment has gone somewhere and is very lonely. He is affectionate and eats whatever he gives him.
