Japanese snack toys display a certain fascination with the natural world, but this fascination is not limited to the cute animals we're all familiar with--they also include sets themed on rare and relatively unknown subjects, such as a series on weird and wonderful creatures of the sea which included the rare lantern fish.
日本食玩對生物世界的著迷，不只侷限在眾人熟知的可愛動物上，更反映在一些鮮為人知的冷僻主題裡。例如曾有廠商推出造型詭異的深海動物系列，包括罕見的燈籠魚等。
