Captain Olimar's Journal
"I recently took a team of blue Pikmin on an expedition to explore a submerged cavern. While exploring this watery cavern, I encountered some very strange phenomena. It was such a strange place that I'm still wondering it is was all just a dream. I found this curious treasure in that cavern, so if it was just an illusion, I'm even more confused. I named that confounding place the Submerged Castle."

Sales Pitch
"Noisier than a spaceship, this wonderful item will make your miserable life 120 percent more exciting."

When found
"Processing... How curious. The wraith completely vanished! But what was it?"

"Surface-object scans indicate the presence of a bright red component!"

When collected
"How insulting... This object's coloring is more eye-catching than my own hull!"

"I shall connect it to the alarm clock our esteemed president was so fond of."

"Processing...complete. I have refitted both objects into a Pluckaphone."

"Now, simply blowing your whistle will inspire Pikmin sprouts to pop up out of the ground."
