Collecting the treasure
Hey! Pikmin logs
“I'm a quiet man. I don't like too much fuss. But sometimes I get the urge to change that about myself. I went to an office party where they had these and tried one, and it wasn't so bad. Where I went wrong was bringing one home with me. I waited for my wife to surprise her with it, and well, suffice to say it wasn't the only earful I got that night.”
