中銀

中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

银 = 艮 + 钅 : Maud Younger spotted a large silver sphere hanging above the entrance to the encampment. She wants to have it and repeatedly throws a golden harpoon at it; to retract the harpoon she uses a chewing gum which she attached to the harpoon, so that it expands to a long rope as she throws the golden harpoon at the silver sphere.
