Captain Olimar's Journal
"I discovered a metallic container. Unfortunately, it was already empty, so it is going to be tough to sell. Some sales talk will be needed for this. Let's see what the ship says about it."

Sales Pitch
"The ultimate in reverse psychology! If it's too open, nobody wants to steal it. Its a shame though, that the contents are so clearly visible."
