The description in the text is somewhat like a pelican, and the signal is transmitted from its belly.
[You walk up to the Big Mouth Duck and take out the Blade of Healing.]
[The Big Mouth Duck, seeing the blade in your hand, trembles in fear, hastily tries to escape, but you forcefully hold it down.]
[Amidst the Big Mouth Duck's sharp cries, you cut open its belly with the Blade of Healing, feel around inside, and quickly find a Green Stone.]
[You obtained 'Moon Stone with Recorded Information' *1.]
[As the Green Stone is removed, the wound on the Big Mouth Duck automatically heals. Its screaming stops abruptly, it looks blankly at its intact belly, then raises its head with fear in its eyes, glances at you, and hastily scurries to the other end of the belly cavity, hiding among a bunch of small animals.]
[You connect the Green Stone to the Mechanical Heart, and a recording automatically plays in your mind.]
