Captain Olimar's Journal
"I found this object squirreled away in an underground complex. Some of these structures demonstrate a high degree of culture. I surmise that each building must have been designed by an artist of great renown. This pink painting rod reinforces my hunch that this civilization appreciated fine art."

Sales Pitch
"No artistic inclinations? No color sense? No worries! This no-hassle art implement was found on a primitive planet. From this day forward, you can be an artist of the ages!"
