Captain Olimar's Journal
"What a strange pattern. When I look at it, I can feel good fortune smiling down on me. If I could just buy a lottery ticket right now, I'm sure I'd win!"

Sales Pitch
"This appears when you have no money to play the lottery, and floats away when you do. The mystic pattern is a magnet for good luck, so at least you can enjoy feeling lucky!"
