Corps of Discovery: Insecta (English)

The Corps of Discovery ventures more to the west to find the woods teeming with giant insects. Only an insecticide suspended in the air can end the threatening masses that threaten to invade the body. The ingredients necessary to concoct such a poison are easily available from the earth itself, but all your precious scientific equipment is back on your boat. So that you can bring the resources back to the boat, you must first take care of the Ranidae, a monstrous creature resembling a frog that is just below the surface of the river, somewhere between the shore and the ship.
