"Oh yeah, better than we just do this boring activity, let's went off to the jungle to looking for a fascinating treasure, maybe there's a fascinating treasure was hidden in this uninhabited island!" said Hidaka while throwing his shovel
"But, it is okay, if we go without telling the captain?" asked Tatsuya
"It's ok! We will go quietly without the captain know, later, he will think that we're go to the rest room, actually, we're wandering in the beach jungle to search a fascinating treasure!" answered Hidaka

"Ok! Let's go!" said Tatsuya in excitement
"Quiet! He will recognize this if you said this too loud!" said Hidaka with whisper voice
"Oh, okay..." said Tatsuya
Tatsuya and Hidaka are wandering to the beach jungle to search the hidden treasure.
While in the beach, Munakata and Fushimi were searching for Hidaka and Tatsuya.
"Oh yeah, did you see Hidaka-kun and Enomoto-kun?" asked Munakata
"No, before, they're here" answered Fushimi
In the jungle...
"The beach jungle little creepy..." said Tatsuya little scared
"C'mon! Let's find the treasure!" said Hidaka with high spirit but, I just smiled

Hidaka and Tatsuya begin to search where the treasure was hidden, looking around in the beach jungle, I felt happy because, I never do like this, while Hidaka bring his binoculars on his neck, but I'm not bring any binoculars I just search it with my own eyes. Suddenly, I and Hidaka heard a strange footsteps so I and Hidaka hide in the shrub.
"Now safe, let's continue!" said Hidaka with whisper voice
We still continue for the treasure, suddenly, Hidaka sees a light from afar.
"There, there I saw a light from that cave, let's go!" said Hidaka

Unbeknownst to them, Munakata and Fushimi spying them from behind a tree.
