Spook Trench

Spook Trench is the third episode of Hero: 108: Reborn.

Synopsis
Big Green receives a message in the bottle from a unspecified race of animals at the bottom of the ocean, and set out on a mission of wary diplomacy.

Plot
A glass bottle is seen floating along the surface of the ocean. Another bottle is seen, this one floating in a fast moving river. Yet another is seen floating amidst ice floes. The scene then returns to the second bottle, characterized by a red stopper, which is seen floating between lilies in a pond. The first bottle is then seen, in a different part of the ocean. The second bottle, seen once again, is fished out of the water by a bear warrior. Meanwhile the original bottle, characterized by a blue stopper, is plucked from the water by one of the Sailor Brothers.

The bottle is next seen brought to Big Green. Within the launch bay are the three Sailor Brothers, Lady Green, Commander ApeTrully, Woo the Wise, Lin Chung, Mystique Sonia, Yaksha, Mighty Ray, and Jumpy Ghostface. One of the Sailor Brothers, having unstopped the bottle, has produced a yellowed message from within. Passing it around, he mentions that it is written in an unusual dialect of human language sometimes used by animals living extremely deep under the water. Lady Green, taking it, reads part of it aloud, noting that it asks for friendship. However, she also notes that it is signed "Pengyou", a name which none of the heroes recognizes. Though they realize that it could be a trap, they nonetheless conclude that they must go to the place indicated on the paper, in case animals really do wish to make peace with humans. Because the Lanternfish King has not returned for many days, the heroes decide that they will need to take Woo's newly upgraded calabash submarine.
