He described growing up making toys, saying he would show them to people to make them laugh. He felt that LocoRoco came from that history. He said, "I wanted to make a game that was easy to play, so that women and children, and people who have never played games before would be interested in playing it. ... I wanted to use AI to make people laugh. That's why I included actions like the LocoRoco stacking up."
