Hey! Pikmin Treasure Log[]
"Today I found a full tank of cleaning solution. I'll polish the S.S Dolphin II until it shines. My most trusted partner doesn't deserve anything less! Postscript: Naturally, the Pikmin have already gotten the S.S Dolphin II dirt again. The ship doesn't mind, though. Maybe the mud is a nice change of pace after all the void of space."
