A tiny look into the buttefrog's evolution: The Pollypillar.
Pollypillars are the hatchlings of the butterfrogs. Opposite to the Caterwog (toads hatchlings), most of the time they are beign born water-locked and with an appearance much too similar to a regular pollywog, except for the six antennae that will later evolve into thick and fleshy hairy appendages that will later evolve into the butterfrog's six's limbs (front legs, back legs and wings/antennaes,etc). It is said that this six appendages hold all the butterfrog's peculiar mutagenic "magic".
The rare land-locked Pollypillars are born with a tiny stubby tail and with tiny and "hairy" 2 to 4 legs, evolved enough to be land mobile as any member of its newborn species.
All Pollypillars look alike up until the middle of its evolutive growing cycle, when its six fleshy hairy appendages are fully grown and ready to start evolving into its new limbs (or whatever other extremities it'll have), that's when they start evolving fully into its final species and start taking on its peculiar characteristics.
