Captain Olimar's Journal
"With the assistance of the blue Pikmin, we found a canister of paint today. I used it to give the ship a fresh coat of paint! But did it thank me? Noooo. As a space pilot, I've always treated my ship like a trusted companion (even if it is a smart aleck). Yet, this snobbish ship has the gall to complain about the color! There's no pleasing it! Forget this...I'm going to bed."

Sales Pitch
"Everyone enjoys decorating in favorite hues, but it's vital to utilize new colors now and then. This tube of goo will surely help you discover a new you!"
