This is a riddle which exhibits the frog’s growth and transformation; it’s said that frogs, immediately after birth, have a tail but no legs or arms, and in old age, do not have a tail but have legs and arms. As frogs are amphibians, their eggs are spawned in water, externally fertilized, and those eggs become tadpoles. After nine months, these animals will change from tadpoles to frogs—tadpoles which originally had no limbs will sprouting arms and legs. These frogs transform from their original black color to green, having a tail to not having tail.
