A number of myths and beliefs about the moon toad subsequently evolved. It is written that the legendary fairy Ch'ang 0 flew up to the moon on the toad's back, and that the spirit of this metaphysical creature gives the moon its soft glow.
據說金蟾是一種蟾蜍精，為月魄之精光；也有人說嫦娥奔月是騎蟾蜍上天的；神話上將月蝕歸因於蟾蜍吞下了月亮，所以古人相信放爆竹、鳴鐘，能讓它把月亮吐出來。
