I had a question about a
Chomping Egg and now I'm following it up with its two metamorphoses: Glutton and Savage.
A Glutton has a round body that tapers to a pointed head, an egg-shaped head with a saw-edged oral cavity (which looks like a huge mouth), and six tube-like legs that each end in a suction cup. Inside that mouth it has a long, flexible tongue to grab and pull in struggling prey. Like its previous form, the Chomper, it is covered in a calcareous shell, but its version is segmented and has a thicker, more resilient membrane underneath to enable its bouts of gluttony.
A Savage is also covered in a segmented shell, with a tough hide underneath, but its bipedal and resembles a dinosaur. It has strong jaws, a stocky frame, and stout limbs that end in sharp talons. Its tail is thick and tipped with a spiky egg-shaped club to act as a counterbalance/slash weapon.
The difference occurs because a Chomper has complex DNA that allows it to become two different things based off its environment: in environments where food is relatively easy to obtain, Chompers metamorphose into Gluttons, but if lean times require Chompers to hunt more and fight for food, then they metamorphose into Savages.
Gluttons are less intelligent because finding food when it's plentiful doesn't require a lot of intelligence. Savages, however, are more intelligent because lean times are best endured through more strategic thought, which allows an organism to more easily find food and win fights.
My question is, are these two metamorphoses feasible for my Chomper? If not, what changes need to be made to make it work?
