The Story
Mon Mon, the water spider, falls in love with a young female water strider he spots gliding freely across the surface of the water one day. But he lives below the surface, and she lives above, and she is ferocious. If he is not careful, she will stab him with her proboscis and suck all the fluid out of his body. Will Mon Mon be able to convey his feelings to her?
